ahol29............Thats like asking how high is high ...lol
There are all kinds of registry cleaners / repair programs out there ......A word of caution ...always backup the registry before deleting anything just in case ......
I use the following .....Registry First Aid .......works well.
System Mechanic 5 Professional ......works well also and has a ton of other nice features .
RegVac.....very powerful.....but its not my favourite.
Advanced system Optimizer V 2.01.4 also works well.....
Best thing to do is do a google search for registry cleaners.....( I just did that and got 361,000 + results)
D/l a few of them that offer a 30 day trial and try them ...then decide what you like ........and go for it ......
Don't get taken in by some of the advertising ......Just because they say its the best ...that doesnt mean squat......
Hope this helps
