Running Win 10 on HP 400-214 desktop upgraded to 12GB RAM and 500GB SSD hard drive. Have been using the free version of Advanced System Care (IoBit) for quite a while but saw some negative comments somewhere about it causing more trouble than it fixes (never had problems, myself) and thought I'd look at other options. A friend recommended CC Cleaner and I downloaded the trial version. It seems to work OK but this AM I ran it, then ran Advanced System Care. The advanced System Care seems to have gone a lot deeper and found more problems. I'd like to go ahead and buy the upgraded version of one of these but, now, don't know which is better.....or....is there something out there better that I don't know about? Suggestions appreciated but it should be known that I am retired and on somewhat of a budget.
