Hope someone can help me. I have a ThinkPad T450 that has a BIOS license for Windows 8.1 RTM Pro OEM. The actual OS currently installed is Windows 7 Enterprise (see the attached screenshot). The question is: if I update using a retail version of Windows 8 Pro and then update to 8.1, will I need to use the retail key or should the OS automatically validate using the existing OEM key installed? I don't want to have to reinstall all my apps again. Thanks in advance.

Windows 7 Enterprise runs entirely on a seperate licensing branch.
Remove Windows 7 Enterprise before installing Windows 8.1 Pro. It will activate right off the shelf.
