I need to (re)activate a fully licensed Windows XP64 installation. But, the MS activation server seems to be off-line. What to do? Why XP? My company has some expensive special purpose HW with custom drivers that are critical for a long term project. There are no drivers available for any other version of Windows, and the company that wrote the current ones is no longer in business. The system is never used for browsing or such, so Internet security is not an issue. I just replaced a broken HD, cloned the contents from a recent backup to a new HD, replaced a dying CD reader, and it seems I tripped MS's activation threshold. Yes, I could go with the XP emulation offered under Win7. But, if I can just get the current WinXP re-activated quickly, that would be better. What I had, worked just fine for many years. If it ain't broke, don't fix it. So, the question is 'I know MS no longer supports XP re patches, updates, & such. But, do they provide a way to re-activate existing installations?'.
