Without this optimization, brief freezes can occur, or the videos can stutter.
NOTE Making this optimization delivers performance improvements in both ESXi 5.x and ESXi 5.1, but
it is required for ESXi 5.1.
What to do next
For Windows 7 and Windows 8 guest operating systems, perform additional optimization tasks. See
“Optimize Windows 7 and Windows 8 Guest Operating System Performance,” on page 37.
Optimize Windows 7 and Windows 8 Guest Operating System
Performance
You can perform additional steps to optimize Windows 7 and Windows 8 guest operating system
performance for remote desktop deployment. All of the steps are optional.
Prerequisites
n
Perform the guest operating system optimization steps that apply to all Windows operating systems.
See “Optimize Guest Operating System Performance for All Windows Versions,” on page 36.
n
Familiarize yourself with the procedure for disabling the Windows Customer Experience Improvement
Program. See “Disable the Windows Customer Experience Improvement Program,” on page 37.
Procedure
1 Uninstall Tablet PC Components, unless this feature is needed.
2 Disable IPv6, unless it is needed.
3 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
4 Start the Registry Editor (regedit.exe) and change the TimeOutValue REG_DWORD in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Disk to 0x000000be(190).
5 Turn off the Windows Customer Experience Improvement Program and disable related tasks from the
Task Scheduler.
6 Shut down the guest operating system and power off the virtual machine.
7 Power on the virtual machine.
What to do next
See “Optimizing Windows 7 and Windows 8 for Linked-Clone Virtual Machines,” on page 38 for
information on disabling certain Windows 7 and Windows 8 services and tasks to reduce the growth of
View Composer linked-clone virtual machines. Disabling certain services and tasks can also result in
performance benefits for full virtual machines.
Disable the Windows Customer Experience Improvement Program
Disabling the Windows Customer Experience Improvement Program and the related Task Scheduler tasks
that control this program can improve Windows 7 and Windows 8 system performance in large desktop
pools.
Procedure
1 In the Windows 7 or Windows 8 guest operating system, start the control panel and click Action Center
> Change Action Center settings.
