Windows 10: User names appearing that look like a security concern -

Wondering about the account unknown entry. Have had an issue with my laptop randomly booting up at night. Just rebuilt it and the name is still there in printer drivers. Found the same in my desktop. Also, it is normal to have double entries for user names? I see that on the desktop which I didn't rebuild but on the laptop which I just rebuilt, there are only single listings of each user names. Have no idea what the account unknown entry could be. Any help would be much appreciated. The image below is from the desktop.TIA

  Type credential Manager on the Windows search bar and select Credential Manager.

Lost myWin10 User Partition Name  

Stu, I do not understand:- 1 The "USER" account appears in many places in Admin 2 bootable user - you've used this term before but it is not a defined term and I don't know what you mean. I can take you through a series of commands to check exactly what each user account thinks is its user folder path. It's going to get too confusing with aliases such as "USER" so, if you are willing, perhaps you can post the results of the checks in PMs to me and I'll be careful to avoid using real usernames in posts here. Step 0 In all steps, ignore user 'accounts' called DefaultAccount, defaultuser0/1/…, Guest, WDAGUtilityAccount Step 1 Run this command Code:

This tells you the SID for each username. Step 2 Run RegEdit, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList Step 3 For each of the SIDs in the Registry SubKeys beginning S-1-5-21, select it and look at its ProfileImagePath entry. Step 4 Step 3 tells you the ProfileImagePath [user folder path] for each SID and you can then look up which user name it relates to using the results of Step 1. So now you can see which user folder path Windows thinks it should use for each username. Please post [here or in a PM to me] the list of usernames, SIDs, user folder paths. Please confirm that those user folder paths get shown in File explorer, C:\Users. Denis
