WTB Windows XP licence

I know...

But I have a PC I need for work and I want a legit licence as I use it for work and want to do updates etc.

Thanks!

How urgently do you need this? Would an X64 version be okay? My place is a mess so it may take some time to find it, but you can have my unused X64 WinXP disk for free if you're not in a huge hurry.
