Looking at the pricing on Newegg for the two versions of 8.1 Pro, I have to wonder why the full version gives you the 64 and 32 bit versions but at a cost of $199, while the OEM 64 bit version is $139. No extra license included in the Retail version, just another $10 CD? I am assuming the 8.1 EULA has not restricted the OEM versions and still allows for changing computers, so if you did not need the 32 bit version of Windows 8.1 Pro, is there a reason to purchase the full version? Such as, does the Retail version have more install or repair options than the OEM version? Is there a difference in the way the two versions are installed, as far as the licensing? Any Special procedures for the OEM version? Thanks.
