Disabling the Windows Update feature avoids some I/O operations to the file system and can reduce the growth of an instant clone's or a View Composer linked clone's virtual disk.
About this task
Evaluate the needs of your environment before disabling Windows Update. If you disable this feature, you can manually download the updates to the parent virtual machine and then use the push-image operation for instant clones or recompose for View Composer linked clones to apply the updates to all the clones.

- In the Important updates menu, select Never check for updates.
