Tried several times again this morning with various settings and as much turned off as possible but same results as before but as said above I will just leave things as they are.
Looked up CCleaner then got all sorts of warnings (http://softwareindustryreport.com/registry-cleaner-reports.php) about downloading more problems and to a novice like me frightened about messing everything up and getting in to real trouble.
My computer works more or less as I want it to so as the old saying goes, if it ain't broke, don't fix it!!!
I could always get a kid in to help me out if needed!
Have a read of this report/review about the s/ware they are saying is the best something that i have never even heard of (a bit like AOL reg cleaners)
Cnet regzooka and have you browsed to the web site, to download it from regzooka ?
i tried but my AV blocked me, reporting it has some kind of attack page, so be careful or better still avoid browsing to it,
As for any reg cleaner , always check what it lists as being wrong after it has scanned the system, if you don't know what something is ,try googling it's name , if all else fails then at least make sure that any changes that you are about to make before selecting fix /repair can be reversed
