This is an old one (2010) that I don’t think many people know about as I was asked by some people recently. When deploying an asset via OSD, System Restore is running so anything that requests it such as Office will get a snapshot. MDT has mechanisms to disable and restore however OSD does not.
I disable System restore during capture then turn it back on as a final step during deployment. Its done for performance as the deployment is sped up greatly as the OS doesn’t do snapshots. I actually have had a person do a System Restore back to within the TS, messy to say the least. So my solution is to disable it then re-enable it.
As mentioned previously, I do a Build and Capture TS that installs the OS WIM, does a few things, patches it and captures it each quarter. One of the “few things” I do is to disable System Restore. Disabling it in the B&C also keeps the WIM used to deploy smaller for easier replication. It is the first thing ran after the ‘Setup Windows and Configuration Manager’ step.
During a deployment TS, it is one of the last things to be ran, I have it before USMT.
