likely a program or service that is still running , you could try to edit your registry or apply this regedit ?
copy paste this text inside the quotes
Windows Registry Editor Version 5.00
into a notepad then save it and change the file extension from . txt to .reg then apply it , If your unsure what your doing I wouldnt try it and I would also suggest you backup your registry or that reg file before you change anything
ask here if you require any help with it ?
