I've had this issue for two days now. I posted in the MS answers forums but got no real fix.
When I first boot up my PC each morning, my user profile I have fails to load and I get Event IDs 1508, 1502, 1515 and 1511 in the Event Viewer.
The issue fixes itself if I restart the PC, but comes back again if I shut down my PC in the night and boot it up the next morning. I've already done the following:
--Checked the registry and this is the only user profile with a "long" SID key (check screenshot below).
--Ran SFC Scan and found no problems.
--Used the error checking tool on the system HDD (no problems found)
A few other notes:
--I have only windows defender (no other antivirus on startup).
--The issue does not happen if I shut down and then boot up the PC during the day. It seems that it needs to stay powered down for a few hours for the profile to fail to load.
--The problem has happened two times already, every morning, but not during any other boots, restarts or shut downs during the day.
--I don't have "hybrid sleep" or "turn on fast start-up" power options enabled.
What might be causing the problem? How do I fix it?
