Please stop using Registry Cleaners!
As a frequenter to the Stardock forums, I see many problems that I'm sure have something to do with the use of Registry cleaners.
Microsoft's stance on Registry cleaners
"Some products such as registry cleaning utilities suggest that the registry needs regular maintenance or cleaning. However, serious issues can occur when you modify the registry incorrectly using these types of utilities. These issues might require users to reinstall the operating system due to instability.
"Microsoft cannot guarantee that these problems can be solved without a reinstallation of the Operating System as the extent of the changes made by registry cleaning utilities varies from application to application."
You may or may not agree with this stance, so here are some important articles from Microsoft you should read.
