i tend to speed up my pc w/ an array of programs, one of which PC Pitstop Optimize (the unregistered version gives you the registry locations and recomended values, so you can do it manually)
i noticed that CCleaner misses a few articles that pitstop finds, some of which are;
ProgID entry: HKCR\VisualStudio.Launcher.sln
tons of TypeLib entries and Interface entries
and some performance+internet tweaks could be incorporated which are shown by the prog.
--edit--
i just noticed they releaced a new version that hides their fixes, i use v1.5.12.2 if you can dig it up somewhere it helps
You must remember that there are Millions of CCleaner users.
CCleaner's objective is to provide the safest product for as many users as possible without intentionally putting users in a position that threatens their computer enjoyment.
The Registry cleaning portion of CCleaner is designed the same way.That is why the Registry
cleaner is considered by "ADVANCED" users as a "mild" or "gentle" registry cleaner.
Manual registry changes can be done incorrectly,at the wrong time,and not in consideration of all the software complications involved.
