Disclaimer: Modifying registry or workgroup subkeys is typically intended for power users, administrators, and IT professionals. It can help fix some issues, however, serious problems can occur if you edit the registry incorrectly. So, make sure to follow these steps carefully. For added protection, back up the registry before you modify it. You can then restore the registry if there is a problem.

I hope one of my four options helps you and I hope you listen to yourself about the results.
