Eileen I have Reg mechanci and I have made it Pro, it fixes any problems in the registry of your computer, if you bought it you will find that it will come up with hundreds - maybe - of problems, you just click repair and that's it, it keeps on working and lets you know when something needs repaired, I got my computer man to hide it so I do it manually now as it was annoying as it kept popping up to tell you 2 problems were found - for instance, and i would have to stop and click repair and continue, it is much better hidden and used manually.

It is a good program and i am glad I bought it, clouldeight give a discount.

I don't know if this helps you at all but I hope it gives a better idea.
