Since updating to Windows 1803, system protection does not work. Restore will not restore from the restore point created during the update. Nor will it restore from any new restore point I create. I get the message:
System Restore did not complete successfully. Your computer's system files and settings were not changed.
Details:
System Restore failed to extract the file (<the path on my system>\OneDrive) from the restore point. An unspecified error occurred during the System Resotre. (0x8007018b)"
This is the same result if I attempt to restore to the point that the Windows 1803 upgrade occurred. And if I attempt to restore to a point I created immediately after the upgrade. And if I attempt to restore to a point created immediately before I attempt
to restore to it. In other words. It is not possible for me to create a restore point and restore to it.
On the rare occasions when I attempted a restore in the past, it worked okay.
I tried this on another machine also recently updated to Windows 1803. The restore point creation then restoration worked correctly. The only obvious difference between the two is that the machine on which the restore worked had only a C:\ drive. The
machine on which the restore fails uses a restore point that covers two drives and the OneDrive file that cannot be recovered is on the non-C: drive.
