10.1.6 Optimizing Desktop OS
vWorkspace includes an application called Desktop Optimizer that can be used to optimize desktop
settings for a VDI environment including disabling unnecessary services.
The vWorkspace Desktop Optimizer is installed with the Instant Provisioning Tools and can be opened
from C:\Program Files\Quest Software\vWorkspace\Desktop Optimizer. The application has
a list of settings or services in the left pane along with a description and reason for modifying in the right
pane.
Windows 8.x Optimization
The Desktop Optimizer tool can be used for Windows 8.x or alternatively, you can use an optimization
script from Microsoft that is available at:

A new feature in Win 8.1 is Automatic Windows Maintenance, which is a feature of the dism tool that
checks the system and application for update compatibility and file integrity. By default, the system
scheduled task runs at 1 A.M. everyday, or any time after 10 min of idle time. When the system runs, the
tiworker.exe process can consume 100 percent CPU on any recently booted desktop VMs, possibly
overloading servers.
The administrator accounts cannot change the services because the services (idle time check and
automatic check) run as a SYSTEM. You must get SYSTEM rights to disable services.
You can still run the checks manually even if the services are disabled. You must have psexec.exe
(sysinternals) on the Master Image VM to fix this problem.
The following are the three scheduled tasks that must be disabled on your desktop template.
psexec \\SERVERNAME -s schtasks /change /tn
"\Microsoft\Windows\TaskScheduler\Maintenance Configurator" /DISABLE
psexec \\SERVERNAME -s schtasks /change /tn
"\Microsoft\Windows\TaskScheduler\Idle Maintenance" /DISABLE
psexec \\SERVERNAME -s schtasks /change /tn
"\Microsoft\Windows\TaskScheduler\Regular Maintenance" /DISABLE
After the desktop template VM has been optimized, shut down the desktop VM to import the template.
