Recently I had been having problems with Vista using too much memory. Specifically such as start5ing IE8 when I had 2.5 gig's. memory free, only to find a short while later having say only 1.7 gig's free. Culled out a lot programs that I either was using or taking full advantage of and that helped for a while. But, after a system crash and a reinstall gee the old familiar registery corruption reared it's ugly head again. One thing I have never quite understand and would like to get a better handle on is why if something is uninstalled from you computer is so much of it left in the Windows Regisyery file. I though (or assumed anyway) that would be removed during an uninstall but, obviously I guess not.
