It looks like "TweakUI" can be used for things like this, which is what I use.
I have been using the same utilities for quite some time that you list for people to use, however i have added another called MRU BLASTER which clears the registry of most recently used web pages, it's actually more of a privacy/security thing then damaging parasites, but it does keep the reg. cleaned of MRU's. The first time i used the utility it found over 900 and cleaned them. You are probably aware it it but just in case here is the web page. Frank Bishop
