regedit window appears and dissapears cant make it stay
Many viruses/worms and some spyware will block the running of MSCONFIG,
Task Manager and the Registry Editor -thus making the removal of the
intrusion more difficult. Since the system tools are blocked by name,
renaming their executables is a workaround. Example: Rename regedit.exe to
regedit.com
Or you can run the tool created by MVP Doug Knox that creates a "backup
set" of those three programs for you:

Also check the system for the presence of viruses using an antivirus
program with current virus definitions. Check for spyware using an
anti-spyware program such as AdAware:
