A week ago I, on impulse, purchased PC Pitstop’s Optimize2 (one year subscription). I know my drive is sluggish with lots of old unused files. So, yes it works, cleans up files and does some internet tweaking. The file clean seemed ok, the internet tweaking may have given trivial increase, I think I might be getting 3600 instead of 3500.

However a week later, while doing some program debugging it was suggested I get a free copy of CCleaner. (Ok, I admit I forgot about it and had posted an entry here a long time ago) Running it was a major surprise, it deleted a lot of files, for example installation and log files going back 3 years. It has somewhat aggressive default settings - it ended up deleting some cookies that lost my automatic logins on some sites - so I had to log in again. Next time I changed the defaults.

Running Optimize after CCleaner does not find any additional files to delete. Of course it is possible that the first time I ran Optimize it found and fixed things that CCleaner would not have fixed, but at this point, I think I wasted my money.

Optimize does do one thing - it does registry cleanup - but it does not seem to be significant enough to pay for that feature
