14.4 Optimizing Desktop OS

Make sure you use the Citrix desktop optimization script which can be downloaded from the Citrix website

which can be used to optimize desktop settings for a VDI environment including disabling unnecessary

services.

Windows 8.x Optimization

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 consumes 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

Turn off the master image and take a snapshot for reference.
