https://support.microsoft.com/help/929135/
A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program. This is similar to starting Windows in Safe Mode, but provides you more control over which services and programs run at startup to help you isolate the cause of a problem.
After performing the clean boot, check which program is causing the problem and try to remove the user, follow the steps below:
Delete the user registry entry from the registry editor:
After touching some registry entries, back up the Windows registry.
- Press the Windows + R keys to open the Run dialog box.
- Type regedit and press Enter.
- On the File menu, click Export.
- In the File name box, type a name that you will remember, such as Registry Backup.
- Select a location where you want to save the Registration Entries (.reg) file.
- Click Save.
- Navigate to:
HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList\
- Click on each of the listed profiles and check the ProfileImagePath entry to verify the associated profile.
- Restart your computer and check if the problem persist.
Try removing it using the command prompt, follow the steps below:
- Open the Start Menu, search for Command Prompt (Admin) and open it.
- Type and press enter:
net user
- This will show you the account names on your system.
- Delete the unwanted account, type:
net user Account Name /del
- Restart and check if the issue persists.
