If CCleaner does more than deleting files I must admit Im completely lost. We need many more pages Moderator. Also the only way I can understand any noticable increase in loading time will be the ONE time prefetch is rebuilding. The same way some say boot time actually increase with prefetch enabled. Time used come back later due to optimzations.
Seems to me you think CCleaner disable prefetch or is suggesting that way is better because of the few mbs saved on hd? Ive never seen such a claim from maker. What I see is a little optional maintaince feature for those programs not accessed in 2 weeks or more, what else is there? All "damage" CCleaner can do is to force enabled prefetch to rebuild again if program is run so much it is considered prefetchable - so ? Not like that is going to happen often is it?
As I said I dont notice any difference so kinda pointless to time and reboot. Without having any idea of loading time I will without any test results believe making pf-file increases. I think we do something else. You will now give your test results, with as many details of setup as possible. No references to other websites or other story - numbers and details please. There are many people here listning so we can do a mass reproduction later
If it fails consider yourself unique...
