After installing Windows 7 RC, when I try to use IE8, I get a "you do not have priviledges to perform this command". I am logged in as administrator already (the only account so far on the computer). I can only use IE8 by right clicking the IE8 icon and selecting "run as administrator". I have a Compaq 5200SL with AMD processor (2.08Ghz), 1G RAM. Everything else so far works great. No problems with Chrome, Safari or Firefox.
