I have a Thinkpad T410 that was delivered with Windows 7 Pro 32-bit. But for using the notebook with 8 GB RAM I need to have 64-bit version. On the COA under the battery it says Windows 7 Pro OA but nothing about 32-bit or 64-bit. Does it mean that I can use a 64-bit installation?
Solved! Go to Solution.

Yes, under Microsoft's licensing, you can use the same Windows 7 Product ID to install either the 32-bit or 64-bit version of Windows 7 on your system, but you cannot upgrade from 32 to 64-bit, so it will have to be a fresh installation.
