Only speaking from my personal experience here, but I just wanted to suggest to those trying Vista (especially people like me who do not have expert knowledge) to stear clear of any registry or file cleaners such as CCleaner or Registry Mechanic. Although these programs seem to pick up problems, I have found that Registry cleaners in particular will say that they have found (for example) 180 problems, but will then only fix half of these, with subsequent attempts at deletion yielding nothing more, suggesting that they are not functioning properly under vista.
I also had a very unfortunate experience with CCleaner, after enabling the cleaning of menu order cache, tray notifications cache, window size and location cache, user assist history, IIS log files and custom folders - I ran a scan and cleaned up. After this I went to both of my drives -properties and ran the windows disk cleanup tool. The windows cleanup tool picked up over 50GB (yes GB) of error reporting files on my main system drive, now I assumed this was an error since the drive did not have anywhere near 50gb of data on it at all, let alone in error reporting files. So I ran the delete anyway. I also did the same on my data drive. After doing so, all of the files on my data drive were deleted and upon restart I realised that crucial system files were missing from my main drive, the system would not boot at all and could not be repaired - prompting another re-install.
Now I probably should have been more careful and not deleted the files, but then it never crossed my mind that Windows cleanup disk utility would ever delete essential system files. A subsequent test with CCleaner produced the same result and so I would urge Vista users not to run this program or anything like it until they or another are confirmed safe to use with Vista.
Oh my control panel was also screwed up - became very slow or impossible to open and the same with the networking centre.
