My sister's PC, an Advent 1800+ with XP-Pro was delivered to me to "sort-out". It was riddled with spyware/malware(lop)/trojans and virus remnants (god knows what she gets up to!) and so I decided that a complete re-install is the only solution. The sticker is present of the back of the PC with her legal XP-Pro code, but just to be safe I also noted the Serial number and ran a code extraction tool which came up with a different serial code number. Having been assured that it didn't come with an XP-Pro disc, it was apparantly pre-loaded I hunted very carefully for the necessary files to create a boot XP disc but they just wren't there. A quick call (risk disclaimer to my sister) and I reformatted/installed using my own copy of XP Pro (2002 edition with SP1a). When I get to the enter key code prompt neither the official one on her case or the one generated by the forgotten key extractor software appear valid to this specific version of XP. Does anyone have any suggestions where I can locate an earlier version of XP-Pro to try? I have the legal key number, I'm assuming it just isn't valid for this version. Thanks, Mark.
