So I just rebuilt a Dell Dimension 4600 with new Gigabyte G31 MB and E5200. I took the old reinstallation CD's and other driver crap too and just figured I would use the 30-Day Free trial of Windows XP (which you get before you activate after installing the OS). Just for sh*ts and giggles I thought I would try activating it using the old License that came with the Dell 4600 from 2003 (I didn't think it would work, but figured the worst that would happen was they would tell me I couldn't activate, so why not?) It didn't work with online activation using the product key on the case, so I tried calling them up. I just gave them the confirmation number that Windows generated and the customer service rep just activated my copy of Windows XP, without asking for a product key or COA or anything. Weird? I thought for sure I was wasting my time but it appears I just got a free license for Windows XP home? Anyone else done this before or know something I don't about the activation process for Windows XP?
