After the Hyper-V role is installed , When you try to create a new virtual machine, it fails to start with the following error:

The virtual machine could not be started because the hypervisor is not running.

Cause: Hardware virtualization or DEP was disabled in the BIOS.

Resolution: Enable Hardware virtualization or DEP in the BIOS. In some cases, the server needs to be physically shutdown in order for the new BIOS settings to take effect.

What is the DEP ?!!! Data Execution Prevention (DEP) is a set of hardware and software technologies that perform additional checks on memory to help protect against malicious code exploits.

Hardware-enforced DEP marks all memory locations in a process as non-executable unless the location explicitly contains executable code. One kind of malicious code attacks tries to insert and run code from non-executable memory locations. DEP helps prevent these attacks by intercepting them and raising an exception.

Hardware-enforced DEP

Hardware-enforced DEP marks all memory locations in a process as non-executable unless the location explicitly contains executable code. A class of attacks exists that tries to insert and run code from non-executable memory locations. DEP helps prevent these attacks by intercepting them and raising an exception.

Hardware-enforced DEP relies on processor hardware to mark memory with an attribute that indicates that code should not be executed from that memory. DEP functions on a per-virtual memory page basis, and DEP typically changes a bit in the page table entry (PTE) to mark the memory page.

Processor architecture determines how DEP is implemented in hardware and how DEP marks the virtual memory page. However, processors that support hardware-enforced DEP can raise an exception when code is executed from a page that is marked with the appropriate attribute set.

Advanced Micro Devices (AMD) and Intel have defined and shipped Windows-compatible architectures that are compatible with DEP.

Beginning with Windows XP SP2, the 32-bit version of Windows uses one of the following:

· The no-execute page-protection (NX) processor feature as defined by AMD.

· The Execute Disable Bit (XD) feature as defined by Intel.

To use these processor features, the processor must be running in Physical Address Extension (PAE) mode. However, Windows will automatically enable PAE mode to support DEP. Users do not have to separately enable PAE by using the /PAE boot switch.

Note: Because 64-bit kernels are Address Windowing Extensions (AWE) aware, there is not a separate PAE kernel in 64-bit versions of Windows.
For more information about PAE and AWE in Windows Server 2003, click the following article number to view the article in the Microsoft Knowledge Base:

283037 (http://support.microsoft.com/kb/283037/ ) Large memory support is available in Windows Server 2003 and in Windows 2000

Benefits

The primary benefit of DEP is that it helps prevent code execution from data pages, such as the default heap pages, various stack pages, and memory pool pages. Typically, code is not executed from the default heap and the stack. Hardware-enforced DEP detects code that is running from these locations and raises an exception when execution occurs. If the exception is unhandled, the process will be stopped. Execution of code from protected memory in kernel mode causes a Stop error.

DEP can help block a class of security intrusions. Specifically, DEP can help block a malicious program in which a virus or other type of attack has injected a process with additional code and then tries to run the injected code. On a system with DEP, execution of the injected code causes an exception. Software-enforced DEP can help block programs that take advantage of exception-handling mechanisms in Windows.

You can effectively "empty" the Recycle Bin from the command line by permanently deleting the Recycle Bin directory on the drive that contains the system files. (In most cases, this will be the C: drive, but you shouldn't hardcode that value because it won't always be true. Instead, use the %systemdrive% environment variable.)

The reason that this tactic works is because each drive has a hidden, protected folder with the name $Recycle.bin, which is where the Recycle Bin actually stores the deleted files and folders. When this directory is deleted, Windows automatically creates a new directory.

So, to remove the directory, use the rd command (r​emove d​irectory) with the /s parameter, which indicates that all of the files and directories within the specified directory should be removed as well:

• For Windows 7 or Server 2008 enter this command:

rd /s /q "%systemdrive%\$Recycle.Bin"

• For Windows XP, Vista, or Server 2003 enter this command:

rd /s /q "%systemdrive%\recycler"

Do note that this action will permanently delete all files and folders currently in the Recycle Bin from all user accounts. Additionally, you will (obviously) have to run the command from an elevated command prompt in order to have sufficient privileges to perform this action.

We can delete the old profiles lying in the system c:\documents and settings\ you can use the below command
delprof /Q /I /D:60

this will delete the profiles not in use more than 60 days

For Windows Vista & Windows 7 above

This is easy using the 'netsh' command.

To block it we would call it like this:

netsh advfirewall firewall add rule name="BlockAIM" protocol=TCP
dir=out remoteport=4099 action=block

Let me explain each setting:

name = The name of the rule. (Pick something descriptive)
protocol = The protocol we are going to block (UDP or TCP for most cases)
dir = The direction of the block. Can be IN or OUT
remoteport = The port of the remote host that is going to be blocked
action = Could be block or allow. In our case we want to block the connection

Once you execute the above code, all outbound requests to any host on port 4099 will be blocked, and it adds an entry to the Windows firewall.

If you want to remove the rule from the command line, you can call netsh like this:

netsh advfirewall firewall delete rule name="BlockAIM"

That is all there is to it. One line to add a rule, and one line to remove.

We use msconfig, regedit, Services manage for start windows fast. But i found a new software who can analyze boot time & diagnose it.

It is called Soluto, and you can download from http://www.soluto.com

The install is simple. Download and run the setup file

Reboot your system, and it will analyze all of the processes that launch at boot time. The cool part is that it looks up each application in a database that is updated by users like yourself - it has a built in wiki editing tool to update information about apps it does not recognize.

When it is finished, you can see all of the programs that impact your boot time. It shows you an exact boot time, and how much time each application takes to launch.

The application is crisp, and almost fun to use. The amount of detail on each application is amazing. The color coding will keep you from making mistakes - something easy to do when you are plunking away while drinking your third egg nog.

When you want to keep an app from running, simply pause it. It will never run again unless you manually launch it.

With a few quick clicks you can pause the applications you don't need and dramatically reduce your boot time.

The file associations for .LNK files on a Windows 7 computer have changed from their default association to another application program, ie. Internet Explorer Picture Viewer, with the result that none of the program shortcut icons or desktop icons launch their respective programs - they all attempt to launch Explorer. Changing the file association on an individual shortcut results in all shortcuts being changed to the selected program. Is there a way to change the .LNK file associations back to the Windows default in order to relate the shortcuts to their respective application program?

Solution - Just download the Registry Fix and merged the .reg file with registry.

preserved when the system is restarted. When used with the PRINT
command, displays the list of registered persistent routes. Ignored for all other commands, which always affect the appropriate persistent routes. This option
is not supported Windows'95. command One of these:
PRINT Prints a route
ADD Adds a route
DELETE Deletes a route
CHANGE Modifies an existing route destination Specifies the host.
MASK Specifies that the next parameter is the 'netmask' value.
NETMASK Specifies a subnet mask value for this route entry. If not
specified, it defaults to 255.255.255.255.
GATEWAY Specifies gateway. interface the interface number for the specified
route.
METRIC Specifies the metric, ie. cost for the destination.
All symbolic names used for destination are looked up in the network
database file NETWORKS. The symbolic names for
gateway are looked up in the host name database file HOSTS.
If the command is PRINT or DELETE. Destination or gateway can be a wildcard,
(wildcard is specified as a star '*'), or the gateway argument may be omitted.
If Dest contains a * or ?, it is treated as a shell pattern, and only
matching destination routes are printed. The '*' matches any string,
and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*.
Diagnostic Notes: Invalid MASK generates an error, that is when (DEST & MASK) != DEST.
Example> route ADD 157.0.0.0 MASK 155.0.0.0 157.55.80.1 IF 1
The route addition failed: 87

EXAMPLES
Examples:
>route PRINT
>route ADD 157.0.0.0
^destination
MASK 255.0.0.0
^mask 157.55.80.1
^gateway METRIC 3
^metric IF 2
^Interface
If IF is not given, it tries to find the best interface for a given gateway.
>route PRINT
>route PRINT 157* .... Only prints those matching 157*
>route DELETE 157.0.0.0
>route PRINT
One way to use this would be as follows: You can't ping the server that you
are connecting to, but you know the ip address to be 127.16.16.10
>route PRINT

Computer networks is an interconnection of computers that allows communication, sharing of resources and information. Each groupings are being managed using different methods for organizing computers in the network.

Windows-based computers inside the network automatically creates a workgroup or domain. Computers on local area network or home networks are always part of a workgroup and computers in businesses and offices are usually part of a domain.

Definitions

Network

A group of devices that communicate either wireless or wired using physical connection such as ethernet cable or a phone line.

Workgroup

A group of computers that are connected on a network and share resources such as printer and files. All computers are peers, means no computer has control over another.

Domain

A collection of computers on a computer network that share a common database and security policy. A domain is administered as a unit with common rules and procedures, and each domain must have a unique name. This makes it easy to make changes because any changes are automatically made to all computers. Domain users must provide a password or credentials each time they access the domain. There can be thousands of computers in a domain and different local networks.

Homegroup

This is a unique feature in Windows 7 in which a group of computers on a network shares pictures, music, documents, and printers. A homegroup is protected with a password.

Whenever you insert a USB drive, CD/DVD, etc into your system, Windows automatically launches an Autorun dialog box which allows you to select an action from the given list. You can browse the content, play media files, etc using Autorun dialog box.

To disable Autorun functionality in Windows:

1. Type regedit in RUN or Startmenu searchbox and press Enter. It'll open Registry Editor.

2. Go to following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

If the above key doesn't exist, create it.

3. In right-side pane, create a new DWORD value NoDriveTypeAutoRun and set its value to any of following according to your requirements:

FF - To disable AutoRun on all drives
20 - To disable AutoRun on CD-ROM drives
4 - To disable AutoRun on removable drives
8 - To disable AutoRun on fixed drives
10 - To disable AutoRun on network drives
40 - To disable AutoRun on RAM disks
1 - To disable AutoRun on unknown drives

4. If you want to disable Autorun on a combination of drives, you'll need to calculate sum of the values. For example, if you want to disable Autorun on CD-ROM drives and removable drives, you'll need to set the value to 20+4=24.

5. If you want to restore the Autorun functionality, simply delete the NoDriveTypeAutoRun DWORD value created in Step 3 Or you can set the default value which is given below:

Windows 2000: 95

Windows XP: 91

Windows Server 2003: 95

Windows Vista, Server 2008 and 7: 91

6. If you want to disable Autorun functionality for all users in your system, use the "HKEY_LOCAL_MACHINE" instead of "HKEY_CURRENT_USER" mentioned in Step 2.

In Windows you can change desktop wallpaper, screen saver, themes and other appearance settings by right-click on Desktop and select "Properties".

If you want to disable all or a few options in Desktop Properties to restrict users or you might want to enable those options in case they are disabled by your system administrator or a virus infection.

Following tutorial will help you in enabling or disabling all or a particular option in Desktop Properties:

A. Disable Themes Tab in Desktop Properties:

Type regedit in RUN dialog box and press Enter. Now goto:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ Explorer

If "Explorer" key is not present, then create it. Now in right-side pane, create a new DWORD value NoThemesTab and set its value to 1 to disable it.

B. Disable Desktop Tab in Desktop Properties:

Type regedit in RUN dialog box and press Enter. Now goto:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System

If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispBackgroundPage and set its value to 1 to disable it.

C. Disable Screen Saver Tab in Desktop Properties:

Type regedit in RUN dialog box and press Enter. Now goto:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System

If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispScrSavPage and set its value to 1 to disable it.

D. Disable both Themes and Appearance Tabs in Desktop Properties:

Type regedit in RUN dialog box and press Enter. Now goto:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System

If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispAppearancePage and set its value to 1 to disable it.

E. Disable Settings Tab in Desktop Properties:

Type regedit in RUN dialog box and press Enter. Now goto:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System

If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispSettingsPage and set its value to 1 to disable it.

* If you want to enable a restricted tab in Desktop Properties, just delete the required DWORD value as mentioned above or change its value to 0 instead of 1.

To hide or show any specific Control Panel applet in Windows.

A: For All Windows Versions except Windows 95, 98 & Me

1. Type regedit in RUN dialog box and press Enter. Now go to:

HKEY_CURRENT_USER\Control Panel\
OR
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\

2. Under this key create a new key with the name don't load , so the new path will be:

HKEY_CURRENT_USER\Control Panel\don't load
OR
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\don't load

3. Now in right-side pane, create new String value. Set its name to the file name of the applet which you want to hide, e.g. if you want to hide Display applet then set its name to Desk.cpl now set its value to no to hide it. If you want to show it again, either set its value to yes or simply delete the String value.

To use the above mentioned method, you'll need to know the .CPL file name of the desired applet. You can search for .CPL in Windows Search or you can use help of following list which contains .cpl file names of almost all default Control Panel applets:
Access.cpl Accessibility
Appwiz.cpl Add or Remove Programs
Bthprops.cpl Bluetooth Devices
Desk.cpl Display
Hdwwiz.cpl Add New Hardware
Inetcpl.cpl Internet Options
Intl.cpl Regional and Language Options
Joy.cpl Game Controllers
Keymgr.cpl Stored User Names and Passwords
Liccpa.cpl Licensing
Main.cpl Mouse
Mlcfg32.cpl Mail
Mmsys.cpl Sound and Audio Devices
Ncpa.cpl Network Connections
Nusrmgr.cpl User Accounts
Nwc.cpl Netware client connectivity
Odbccp32.cpl ODBC Data Source Administrator
Powercfg.cpl Power Options
Sysdm.cpl System
Telephon.cpl Phone and Modem Options
Timedate.cpl Date and Time
Sapi.cpl Speech
Wuaucpl.cpl Automatic Updates
Wscui.cpl Security Center or Action Center

B: For All Windows Versions except Windows 95, 98 & Me

1. Type regedit in RUN dialog box and press Enter. Now go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies

2. Look for a key "Explorer" under it. If its not present, then create a new one and give it name Explorer.

3. Select "Explorer" key and in right-side pane, create a new DWORD value DisallowCpl and set its value to 1

4. Now create another new key under Explorer key with the name DisallowCpl so the new path will be:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ Explorer\DisallowCpl

5. Select "DisallowCpl" key and in right-side, create new String value with name 1 and set its value to the applet name which you want to hide.You don't need to use the .cpl file name of applet in this method. You have to put the applet label which you see in Control Panel.

e.g., If you want to hide AutoPlay applet, then create a new String value, give it name 1 and set its value to AutoPlay. If you want to hide more applets, then simply create more String values with names 2, 3 and so on and set their values to the applet label.

C: For All Windows Versions except Windows 95, 98 & Me

In this method, you'll tell Windows which applets should be visible and Windows will automatically hide the rest.

Its useful when you want to show a few specific applets and want to hide remaining applets. So you just need to create a few String values to tell Windows which applets you want to show. It'll save your valuable time.

1. Type regedit in RUN dialog box and press Enter. Now go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies

2. Look for a key "Explorer" under it. If its not present, then create a new one and give it name Explorer.

3. Select "Explorer" key and in right-side pane, create a new DWORD value RestrictCpl and set its value to 1

4. Now create another new key under Explorer key with the name RestrictCpl so the new path will be:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ Explorer\RestrictCpl

5. Select "RestrictCpl" key and in right-side, create new String value with name 1 and set its value to the applet name which you want to show.You don't need to use the .cpl file name of applet in this method. You have to put the applet label which you see in Control Panel.

e.g., If you want to show AutoPlay applet, then create a new String value, give it name 1 and set its value to AutoPlay. If you want to show more applets, then simply create more String values with names 2, 3 and so on and set their values to the applet label.

Now Windows will only show the applets which you mentioned in String values, other applets will be hidden.

D: For Windows 95, 98 & Me

1. Open "%windir%\Control.INI" file. Where "%windir%" denotes Windows folder which is present in system drive where Windows is installed.

2. You'll see a line saying [don't load] in the file. If you can't find it, then create a new line at last.

3. Now under this line, you can set .CPL file name of your desired applet which you want to hide in following format:

filename.cpl=no

e.g.,

If you want to hide Display applet, then the syntax will be:

desk.cpl=no

You can create similar lines for other applets which you want to hide. The .CPL file name can be obtained from the list mentioned in A.

Add your name at top of the menu and can open any program, Explorer, Documents folder or User Accounts by clicking on it in Windows 7 Desktop Context Menu

Steps:

1. Type regedit in RUN or startmenu search box and press Enter. It'll open Registry Editor.

2. Now go to:

HKEY_CLASSES_ROOT\DesktopBackground\Shell

3. Now we'll need to create a new key under "Shell" key. Right-click on "Shell" key and select "New -> Key". Give the new key any desired name e.g. "Yash" (without quotes).

4. Now in right-side pane, change value of "Default" to your desired name which you want to show in Desktop context menu. We have chosen !!~~YASH~~!! in our example.

5. Now right-click on the new key which we created in step 3, e.g. Yash and select "New -> Key". Give the new key name of command.

6. In right-side pane, change value of "Default" to explorer.exe if you want to open Explorer by clicking on it.

7. To set an icon for the shortcut, select the key created in Step 3 and in right-side pane, create a new String value "Icon". Set its value to your desired icon. We have set it to imageres.dll,207.

*To set its position in the context menu, create a new String value "Position" and set its value to:

Top (To show it at top)
Bottom (To show it at bottom)

Add "System Properties", "Task Manager" and Many Other Useful Shortcuts in Windows 7 Desktop Context Menu

Steps:

1. & 2. are same

3. Now we'll need to create a new key under "Shell" key. Right-click on "Shell" key and select "New -> Key". Give the new key any desired name e.g. "Folder Options" (without quotes).

4. Now we'll need to create another new key. Right-click on the new key which we created in the last step e.g. Folder Options and select "New -> Key". Give the new key name of "command".

5. Now select "command" key and in right-side pane, you'll see "Default" String value. Double-click on it and set its value to as following:

control folders

6. That's it. Now you'll have a new option "Folder Options" in Desktop context menu.

7. You can use the same steps 3-5 to add other options. Simply give the desired option label in Step 3 and set the required command in Step 5. Following are the required codes which you'll need to provide as "command" in step 5:

Administrative Tools: control admintools

Change Cursor: control main.cpl,,1

Change Date / Time: control timedate.cpl

Change Regional Settings: control intl.cpl

Folder Options: control folders

Fonts: control fonts

Internet Options: control inetcpl.cpl

Network Connections:control ncpa.cpl

Power Options: control powercfg.cpl

Printers: control printers

Programs and Features: control appwiz.cpl

Registry Editor: regedit

Security Center: control wscui.cpl

Security Configuration: msconfig

System Properties: control sysdm.cpl

Task Manager: taskmgr

Task Scheduler: Control schedtasks

Turn Firewall On / Off: control firewall.cpl

User Accounts: Control userpasswords

User Accounts Classic: Control userpasswords2

8. That's it.

9. You can add any other desired control panel applet using the same way.

Add any application shortcut in desktop context menu of Windows

Steps:

1. to 4. are same

5. Now select "command" key and in right-side pane, you'll see "Default" String value. Double-click on it and set its value to as following:

C:\Program Files\Windows Media Player\wmplayer.exe
C:\Program Files\Winamp\winamp.exe
etc...

6. Thats it. Now you can check your favorite application shortcut in desktop context menu.

7. You can create as many shortcut as you want. Simply create a separate key for all the applications.

Add Cascading Menus in Desktop Context Menu:

PART 1: Creating cascading menus and adding programs shortcuts

1. & 2. are same

3. Now we'll need to create a new key under "Shell" key. Right-click on "Shell" key and select "New -> Key". Give the new key any desired name e.g. "Menu1" (without quotes).

4. Now select this newly created key "Menu1" and in right-side pane, we'll need to create following 4 String values:
MUIVerb
SubCommands
Icon
Position

* Icon and Position are optional but MUIVerb and SubCommands are compulsory.

* MUIVerb contains the name of cascading menu which will be displayed in the context menu. You can set its value to any desired name like Apps, Browsers, etc. Feel free to set any name.

* SubCommands contains list of commands separated by semi-colon (;) which you want to show under cascading menu. You can't add any program shortcut directly. First you'll need to give any desired command name in this list and after that you'll need to register it using PART 2 so that it can start working.

5. If you are confused about "SubCommands" String value, this point will clear all your doubts.

Suppose you have created a cascading menu "Apps" using Step 3 and now you want to add Notepad and Calculator shortcuts under it. In this case, you'll need to set following as "SubCommands" value:

notepad;calc

Above value can be changed according to your requirement. You can use np;ca instead of notepad;calc. But you'll have to use the same name while registering those commands using PART 2.

* If you want to put a separator between menus, just use Pipe symbol (|) between commands. For example, notepad;|;calc.

6. Icon String value can be used to show an icon for your cascading menu. We have set its value to explorer.exe that's why its showing Windows Explorer icon for the "Apps" cascading menu.

7. Position String value can be used to define the position of cascading menu in the context menu. By default the cascading menu is shown in the middle but you can set its position at Top or Bottom with the help of "Position" String value.

8. You can create more than one cascading menus using Step 3 and 4.

PART 2: Adding functionality to the shortcuts by registering them

Once you have added the program shortcuts to cascading menus, you'll need to register the commands mentioned in "SubCommands" String value using following method:

1. Go to following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\Shell

2. Under this key, we'll need to create new keys for each command mentioned in "SubCommands" String value.

We used 2 commands : notepad and calc, so we'll need to create 2 keys under "CommandStore\Shell" key with the same names notepad and calc.

3. Once you create the key, select it and in right-side pane set value of "(Default)" to the name which you want to show in cascading menu. For example set its value to Notepad or Calculator or any other desired string.

4. If you also want to show an icon for it, create a new String value with the name icon and set its value to program's EXE file path or any other desired icon. For example, to show Notepad icon for Notepad shortcut, you can set value of Icon to notepad.exe

5. Now final step! Create a new key under the recently created keys, e.g. notepad or calc and give it name command.

Click on it and in right-side pane, set value of "(Default)" to the path of your desired program's EXE file. For example, if you want to open Notepad when you click on "Notepad" entry in cascading menu, set value of "Command" to notepad.exe

* Notepad is a Windows application, so you can omit the full path but if you want to execute any 3rd party program, you should give full path of its EXE file.

That's it. Now you'll see your desired cascading menus containing your favorite programs shortcuts in Desktop context menus.

* Define the shortcut icon and position.

To set an icon for the shortcut, select the key created in Step 3 and in right-side pane, create a new String value "Icon". Set its value to your desired icon or simply put the path of program's EXE file and it'll automatically show its default icon.

To set its position in the context menu, create a new String value "Position" and set its value to:

Top (To show it at top)
Bottom (To show it at bottom)

*To remove any option, simply delete its key.

Hide user name for the user that has locked the computer:

1. Start Registry Editor.

2. Locate the following key in the registry:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System

3. If it doesn't exist, on the Edit menu, point to New, click DWORD Value, and then add the following registry values:

Value name: DontDisplayLockedUserId

Value data: 1, 2 or 3 (see below)

Base: Decimal
