Can I delete temporary User Profiles and folders from Users directory?

I am trying to determine whether I can delete TEMP User Profiles. One of my Win 10 Pro machines was updated to Version 1903 last night. After rebooting and trying to log in, I received the message "The User Profile Service service failed the sign-in." I was about the try repairing the registry but decided to just do several reboots. For some reason, this fixed the sign-in issue. However, now I notice that four temporary User Profiles were created, all starting with TEMP.

Looking at the registry entries in ProfileList, I see the entry ending in 1001 (which is for user haisler) and the one ending in 1003 (which is for user adminwh), and these look OK and work OK for sign-in. So my sign-in problem is fixed. None of the entries in the ProfileList are connected to the TEMP user profiles.

Looking at folders/files stored for the User profiles starting with TEMP (like Desktop, Documents, etc), I don't see any files there the are connected to the main user (haisler).

So Questions: Is it safe to delete the four folders starting with TEMP in the Users directory? Is there any other step that needs to be taken to delete these four User Profiles and associated files?

It should be safe but first rename it by adding .old to the end wait a week to be sure there are no problems if there are you can role back then you may need to take ownership to delete them

Refer to

--- I've used that a couple of times successfully
