You don't need to 'deactivate' it, just uninstall it from, your PC. When you
sell it just mention to the buyer that the software had originally been
activated and that, when they install it, they may have to choose telephone
activation to get the product activated. This certainly isn't a problem.
Having said all that, I would much prefer the Retail version over the OEM
upgrade. The OEM copy cannot be moved to another computer, whereas a retail
copy can.
