to upgrade Vista HP? I have an Intel D945 mobo that I have read here that is impossible to add a SLIC table to. The PC is a Gateway that I had XP on then I put a full Vista HP on it. I have read that I could use a OEM ultimate key and just do the upgrade and activate. I have an inkling that it will not work, and I figured this was the place to ask the question. BTW, I have really enjoyed the reading here, very useful stuff.
