But it can't. Getting this error. Have tried turning UAC all the way to lowest setting, didn't help. I *AM* the administrator of the machine. If you have a work-around let me know, otherwise I'll roll back this Windows update. This pops up every time the machine is rebooted. Could it be related to the fact that I only have 7.95GB free space on the OS drive? I have more disc space on other drives, but not on the OS drive. Does it need to be on the OS drive to work? Windows updated to version 1909, no problems before that. Don't know what they screwed up, but it's Windows, so the answer is probably at least a quarter of the usefulness and usability.
