As for your PC, running a registry cleaner is a craps shoot. Sometimes it works, sometimes it doesn't. You lost on the dice roll this time. Sorry. Hope you made a backup of your system like most all the programs recommend... + 0 Votes Or, seanferd 2 years ago removed bad entries made by malware, which then broke things. Happens all the time with malware removal, sometimes with registry cleaning. Backups are always a good idea. So is contacting the vendor when there is a problem. + 0 Votes Try System Restore... wizard57m-cnet Moderator 2 years ago Most of these registry cleaners at least create a restore point prior to making changes. Simply choose a restore point prior to the time you ran the registry cleaner. In the future, take my advice, forget about registry cleaners in general. They regularly fail to deliver on promises of speeding your system, and as you can bear witness, can result in loss of needed functionality. The ONLY time I recommend using one is after cleaning up from a malware infection, and then review the changes the registry cleaner proposes.
