About every ten days or so, my computer, with Windows XP, especially internet explorer (#8 I think) gets slower and slower so I run the free version of ccleaner...and it speeds right up for another week or ten days....Almost all the files "cleaned" are under the internet explorer category. I always install Microsoft updates.) So yesterday, I again ran ccleaner, again my computer seemed normal afterwards, but I decided to also check with "doublemyspeed.com" another cleaning tool .. Supposedly it found 515 "problems" but I have no idea what they mean. items found: system software settings: 291 user software settings: 126 Activex,OLE and com settings: 55 Invalid file associations:24 uninstall section : 15 So should I spend about $30 for a year of "doublemyspeed.com" for to fix those supposed "problems"?? To my knowledge I have NOT manually selected any user settings..whatever Microsoft provided is what I use.
