I have been running the x64 Ultimate RTM using a loader for a few months now and really like it. However I am just paranoid that one day MS will crack down and I wont be able to get the new SP or updates. The Slic Bios for my MB (IP35 Pro) has been posted here to have issues. So I ordered the $29 student Home Premium and am considering installing it. What will I lose by using home vs Ultimate ? My system has 8GB of ram which is the max the MB will allow, I can't think of any reason I really need the Ultimate version but wanted to check here first.
