The TargetOSOptimizer tool reconfigures various Windows functions to optimize the performance of the operating system for virtual desktops. Optimization of the master VM is typically performed before the desktop catalog is created.
To optimize your master virtual machine, select the option to optimize the desktop when you install the Virtual Desktop Agent. This applies a predetermined set of optimizations specifically recommended for pooled and dedicated machines as part of the Virtual Desktop Agent installation process.
To apply additional optimizations to the master virtual machine at a later date, run the TargetOSOptimizer tool manually.
Optimizations are applied either through changes to the Windows registry or programmatically by disabling specific features. Some optimizations are only applicable to certain versions of Windows or, for physical machines, specific hardware such as particular network adapters.
A backup file named optimizations.reg is stored in the installation folder for the TargetOSOptimizer tool, typically located at C:\Program Files (x86)\Citrix\TargetOSOptimizer. Apply this file to the Windows registry to revert the most recent set of optimizations on the master virtual machine..
