Hello, and thanks for your reply!
Don't worry about deleting the other post, I rephrased my questions here.
I understand the concern you raise, and I know that registry cleaning is something touchy.
I thought that maybe it could be useful to advanced users, who are aware of the risk of reg cleaning but who still want to do it in the most non-intrusive manner.
I thought about it because through a scripting language (the powerful autohotkey) and various utilities I've been able to completely automate my computer's maintenance, everything I deem useful is scheduled, junk files are deleted automatically, the registry is defragmented etc etc.
The last step would be to have reg cleaning run unattended, then all clean-up operations would be performed absolutely automatically.
I hope that it can be considered in the future, maybe with some extra warnings and disclaimers in the doc files.
Cheers!
