I bought a copy off the web of WinXP Pro SP1. When I went to upgrade, Microsoft told me I did not have a valid key. I went back to the vendor and they led me to a patch file that worked after installing and allowed me to function normally. I have since lost my hard drive before I could do another recent back up and lost that patch file. I cannot find the vendor on line again (BIG surprise) and don't remember where that patch file came form. Does anyone have any ideas?
Thanks
