How many computers are linked to this account?
Please check system journal (Event Viewer) for possible reasons of disactivation. DistributedCOM errors should be ignored.
Or save system journal to evtx file and share it to OneDrive for analysis.
There are only two computers on this Microsoft Account. The third one on the network is linked to a separate account.
I have saved the file, but I will have to set up OneDrive before I can post it.
