May I please break in here and remind all of you that it is very unwise to casually suggest to users to enter Regedit and clear or edit settings.
The very great majority of people posting here are not experienced users and can easily do a lot of harm to the installed software... INCLUDING MAKING THEIR OPERATING SYSTEM INOPERATIVE.
Regedit is not something to play in.
Any advice regarding working in Regedit should include full details and step-by-step instructions... AND a clear warning of the possible loss of not only installed applications but the Operating System itself.
