Clean safely, backup and restore the Windows registry with Wise Registry Cleaner
Wise Registry Cleaner cleans junk left by program installations, etc. It scans the Registry, flagging orphaned or bad Registry entries, and shows you the name and values for each.
It identifies Registry entries that may be dangerous to delete, and those that are safe to delete, so you can distinguish between the two.
It also lets you decide which entries to delete, and which to keep.
Wise Registry Cleaner can also backup your Registry before a scan, so that you can restore it, if the program causes any problems, or just to have a copy for safety.
