User folders reappear after delete

I have a WIN7 computer that was a member of a domain but has been removed from the domain and is just a member of a workgroup and is going to be used as a target computer for a ghost image.  When looking at the C:\Users folder, there are 6 old domain user folders that exist.  If I look at the profiles, those account do not exist.  I can delete the folders successfully but after a restart, they reappear.  I have checked the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and they do not exist there.  
How can I permanently get rid of these user folders so they do not reappear after a reboot.

Any help will be appreciated.

1. Run Disk Cleanup and delete all items or use another powerful tool. Then restart. Will they reappear?
2. Check if these folder are synced from another location. Check if there is a relation with Offline files.
3. Move these folders to another location, rename them and delete. Will they reappear after restart?
4. Perform clean boot without any services and startup items. Will they reappear?
5. Get into Safe Mode, take ownership over these folder and delete them for good.
6. Run deep virus scan.

I had to boot to safe mode, take ownership and then delete the folders.  This worked and they folders do not reappear after a restart.
