You do not need to use the Windows System Restore feature if you use View Composer refresh to restore linked-clone OS disks to their original snapshots.

When the operating system is idle, System Restore does not have a visible impact on OS-disk growth. However, when the operating system is in use, System Restore generates restore points based on system use, which can have a significant impact on OS-disk growth.

The function of Windows System Restore is the same as View Composer refresh.

As a best practice, you can disable Windows System Restore and avoid unnecessary growth in your linked clones.

If you do not use refresh, evaluate whether it is best to leave System Restore active in your View environment.
