Yeah in my testing after install system restore is not turned on, but once i turn it on and create restore point Im able to complete a system restore successfully, and np we are all here with an interest to learn something
I tried your GamerOS 10 preset (with Windows 11) and I could not complete the installation. There was an error during the setup phase that was unrelated to the TPM check.
I'm still in testing here, but I seemed to narrow down the dependency for Backup and Restore to something inside Components -> Networking and/or Remoting & Privacy. PhsMu may be on to something when they mentioned a possible relation to SMB dependencies...
edit:
I've narrowed it down to Remoting and Privacy. I went and chose everything I thought was good to remove, found that Windows Backup failed, and am now backtracking through about 23 different options, just a few at a time. Unfortunately, each reinstallation via VM takes about an hour to fully test out.
edit 2:
I'm finding that whatever removed component is breaking compatibility with Backup may be undocumented / unintended. None of the components in NTLite mention compatibility in any way. I fired up the Event Viewer when the backup runs and found that svchost.exe crashes with an error that is not referenced on the internet anywhere. I'm still messing around with finding which component is causing the issue.
edit 3:
Nailed it down to Windows Error Reporting, Rights Management Support, Packet Monitor, and/or Diagnostics and Troubleshooting.
edit 4:
It's the Windows Error Reporting service. Now I'm seeing if it's Troubleshooting support or the Telemetry Client specifically. After that, I will continue on with a regular install and see if there's anything else that breaks support for Backup.
edit 5:
Components -> Windows Error Reporting Service -> Problem Reports and Solutions Control Panel Support must be kept for Windows 7 Backup and Restore to remain working. Now that I believe I've found the root cause, I will go ahead with the GamerOS preset and continue testing.
