I wouldn't normally recommend a registry cleaner as they sometimes do more harm than good. In future, if your going to clean your registry, you should create a new restore point and backup the registry
first. For backing up the registry I like to use ERUNT
If you’re clean, you should create a new Restore Point
to prevent possible re-infection from an old one.
> System Tools
and click System Restore
. Choose the radio button marked Create a Restore Point
on the first screen then click Next
. Give the Restore Point a name and then click Create
. Then use Disk Cleanup
to remove all but the most recently created Restore Point. Go Start
and type: "Cleanmgr" (without the quotes). Click Ok
> More Options
tab > Clean Up
in the System Restore section to remove all previous restore points except the newly created one.
