Disable the Windows Update Service on Windows 7 and Windows 8 Virtual
Machines
Disabling the Windows Update Service can reduce the number of files that are created and writes that occur
when updates are downloaded and installed. This action can reduce linked-clone growth and reduce IOPS
in linked clones and full virtual machines.
Disable Windows Update Service if you refresh and recompose the linked-clone desktops. A refresh
operation restores the OS disks to their original snapshots, deleting the automatic Windows updates. A
recompose operation recreates the OS disks from a new snapshot that can contain Windows updates,
making automatic Windows updates redundant.
Do not disable the Windows Update Service if you do not use recompose to install Windows updates in the
linked clones.
Prerequisites

5 Deselect Give me recommended updates the same way I receive important updates.
6 Deselect Allow all users to install updates on this computer and click OK.
Disable the Diagnostic Policy Service on Windows 7 and Windows 8 Virtual
Machines

desktops.
