  1. "Account Unknown" in Profiles may be a duplicate entry


    I noticed when looking at the User Profiles on my computer that there was an "Account Unknown" entry. Normally I would have deleted it but because of the significant size and that it was larger than my "real account" I figured I need to check it before deleting.Here's what the user profiles looked like initially:Account Unknown 164Gb Local Local 12/26/2024xxxx\David 153Gb Local Local 12/26/2024I added 31Gb of files to my Documents folder and this is what they look like now:Account Unknown 195Gb Local Local 12/26/2024xxxx\David

    Delete "Account Unknown" from "System Properties" - "User Profiles"?

    My "User Profiles" list includes 3 entries labelled "Account Unknown". Looking at the profiles listed in the registry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList, it seems that the accounts are three accounts with SIDs starting with S-1-5-80, which were created when I installed SQL Server Express as a test. I have since uninstalled SQL Server Express. Is there any reason not to delete these 3 profiles? Is there any way to be sure that the 3 "Account Unknown" entries in the "User Profiles" really correspond to the registry entries I think they do?

    "Account Unknown" in Profiles may be a duplicate entry

    unknown account

    Hi I have noticed on all Documents/videos/photos in properties/security there is an unknown account as per screenshot. If I try to delete it ,I then get a message splash as per second screenshot. Is there a way to identify this "unknown account" and delete it. I investigated registry profile image path and it lists this account as myself-strange? Thanks I am using W10 21H1 Build19043
