It is the one I have and use...never had an issue with it.
Tried some others and they seemed kind of confusing and all that.
Select for regsrub to find all problems after it has found everything which may take a while( I have seen 500 items)
Then select all...then select...fix all selected items and it will go through the system and repair or remove them as need be....
I always give it a good 24 hours and then open it back up click on the restore and then remove(delete) the stored back-up as there has never been an instant for ne to use the backup function..I get rid of it.
