Disabling the Windows System Restore 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

With System Restore, you can revert a machine's state to a previous point in time. You can achieve the same result with the push image operation for instant clones and the recompose or refresh operation for View Composer linked clones. Furthermore, with instant clones, when a user logs off, the machine is recreated, making a system restore unnecessary

The following steps apply to Windows 7 and Windows 8. The steps might vary on different Windows operating systems.
