Previous versions of Windows accept the recovery disk. Some, finding the OEM installation, don't even ask for it. And from what I recall, all upgrades offer to create a roll-back to the previous OS.

It's been awhile, and I'm sorry for the somewhat non-committal answer, but I'd go ahead and try it, myself... unless someone else posts information to the contrary here. Frankly, I suspect an awful lot of "Pro" upgrade disks are used this way, and I'd be surprised if it didn't work.

BTW, is your disk a Service Pack 2 disk, or have they got SP3 disks on the market yet? If not, be ready for the SP3 download... :)
