Can I sell my windows 7?

Stupid question

Can I sell my used win 7 home premium (full version)
as a chap I work with says I cant, as it will not authenticate, due to being on a different OP address and different computer gear.

I have ditched my PC, and the new owner has used his win 7 disk, so mine is now unused.

IF it is a Retail version, then yes you can sell it. It will activate just fine. OEM versions you cannot sell.
