Optimize Windows 7 Guest Operating System Performance for VMware

These recommendations include turning off the screen saver and not specifying a sleep timer. Your organization might require the use of screen savers. For example, you might have a GPO-managed security policy that locks a desktop a certain time after the screen saver starts. In this case, use a blank screen saver.


Prepare a guest operating system for desktop deployment.

First Procedures:

Disable any unused ports, such as COM1, COM2, and LPT.

Adjust display properties.

Choose a basic theme.

Set the background to a solid color.


Set the screen saver to None.

Verify that hardware acceleration is enabled.

Select a high-performance power option and do not specify a sleep timer.

Disable the Indexing Service component.


Indexing improves searches by cataloging files. Do not disable this feature for users that search often.

Remove or minimize System Restore points.

Turn off system protection on C:\.

Disable any unnecessary services.

Set the sound scheme to No Sounds.

Set visual effects to Adjust for best performance.

Open Windows Media Player and use the default settings.

Turn off automatic computer maintenance.

Adjust performance settings for best performance.

Delete any hidden uninstall folders in C:\Windows, such $NtUninstallKB893756$.

Delete all event logs.

Run Disk Cleanup to remove temporary files, empty the Recycle Bin, and remove system files and other items that are no longer needed.

Run Disk Defragmenter to rearrange fragmented data.


Next Procedure


Uninstall Tablet PC Components, unless this feature is needed.


Disable IPv6, unless it is needed.


Use the File System Utility (fsutil) command to disable the setting that keeps track of the last time a file was accessed.

For example: fsutil behavior set disablelastaccess 1


Start the Registry Editor (regedit.exe) and change the TimeOutValue REG_DWORD inHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Disk to 0x000000be(190).


Shut down the guest operating system and power off the virtual machine.


Change the virtual machine video card RAM setting to 128 MB.

Power on the virtual machine.
