Can i use the upgrade version of windows 7 as an oem

Solution
Is it technically possible? Yes

Will you have a legal/licensed install? Probably not


The upgrade version needs to be applied to an existing install of XP or Vista or whatever versions of windows fit the upgrade license criteria.

No. Unless the customer already has a Windows license for the computer that you plan to upgrade, then it would be okay. For clean installs, stick to either Retail or OEM versions of Windows.
