I've run Belarc, and it tells me quite a lot of hotfixes that need to be reinstalled.
Windows update didnt tell me a lot of these.
I also ran Drivermax, and it tels lme there's new version of a lot of my drivers.
Wonder if people generally trust these two. Some of the hotfixs say they can't be installed when I try to - some say already installed - others just wont install, and Belrc tells me they are still in need of replacement.
