A fellow MVP has written a neat program that lets you pick and choose which programs should be blocked on startup. I know when I have UAC enabled, NHC (Notebook Hardware Control) always gets flagged as a blocked program. Thankfully the newer versions are Vista compatible so I don't need it to be blocked anymore.
You can download the English version here and the French version here.
I originally spotted this in the newsgroups and in the blog posting here.
I am also excited to announce that my postings are now mirrored at the MSMVPS website.
