Error when removing a user profile in Windows 10?

Question

I have tried to:

• Remove a user from the Control Panel, but the C:\Users\bob folder still remains.

• Manually deleting it works sometimes if I delete all subfolders, but some users folders do not allow me to delete:

  C:\Users\bob\AppData\Roaming\Microsoft\Windows\Libraries

  even if a I take ownership...

• Deleting the the Account Unknown from System Settings following
  instructions from this post , throws the error

  Profile not deleted completely. Error - The directory is not empty.

EDIT: I probably should have mentioned that this is in a Windows 10 Home edition.

Answer 1

Found the answer here

The steps:

1. WIN-R to open the Run Window and type services.msc
2. Find the Windows Search service and stop it

You may notice that the "Libraries" folder disappears from \appdata\roaming\microsoft\windows\Libraries when you do this.

3. Delete the User folder!
4. Right click Windows Search in the services window again and START it.

Answer 2

Following is a copy of the solution How to delete domain user profile from a computer? which should work equally well on a local computer with Windows 10.

• Open up "Control Panel | System and Security | System"
• In the dialog click on "Advanced system settings" (requires Admin rights)
• The "System Properties" dialog will be displayed
• Make sure you are in the "Advanced" register
• In the "User Profiles" section click on "Settings"
• The "User Profiles" dialog is displayed
• Select the account. Hit Delete.

Faster:

• Start | Run
• sysdm.cpl
• switch to register "Advanced"
• In the "User Profiles" section click on "Settings"
• The "User Profiles" dialog is displayed
• Select the account. Hit Delete.

If you have a greyed out button it means that the registry hive has not been released by the operating system, as pointed out by @joeqwerty in the original post.

You could always just delete the C:\Users\[ACCOUNT] directory, but that leaves some registry entries behind that have to be manually deleted.

Deleting any leftover Registry Keys

• Open Regedit with Administrator Permissions (Runas Administrator)
• Select the HKEY_USERS branch
• Search for the Domain Account without the domain (e.g. login = DOMAIN\ACCOUNT then search for ACCOUNT)
• Keep on searching until the status bar shows Computer\HKEY_USERS\[SID]\Software\Microsoft\Windwos\CurrentVersion\Explorer\Shell Folders
• There should be a large list of your ACCOUNTs folders e.g. C:\Users\ACCOUNT\Desktop

You are in the right HKEY_USERS\[SID]\Software\Microsoft\Windwos\CurrentVersion\Explorer\Shell Folders branch if the ACCOUNT in "Shell Folders" matches the ACCOUNT you just manually deleted form the C:\Users\[ACCOUNT] directory. This branch [SID] can be exported and/or deleted to clean up the last of the user profile.
