Hello! I'm running Windows 8 Single Language 64-bit (OEM) and I plan to do a clean install with Windows 8.1. I presume since my Windows 8 is SL, I can only install a Windows 8.1 SL version. Is this really the case or is it possible to install a more feature-packed version of Windows 8.1 on my machine (for instance Windows 8.1 x64 Multi-lang) and have it activated from my embedded key? (I figured since I'm doing a clean install, I might as well make the most out of it.) Assuming that I can only install Windows 8.1 SL (which I strongly suspect), I've tried searching the forum for the download links with the latest versions and have found the following two: forums.mydigitallife.net/threads/47732-The-Windows-8-1-(-amp-related)-Repository#a7viiforums.mydigitallife.net/threads/53855-Windows-8-1-with-Update-ESDs-Repository?p=900356&viewfull=1#post900356(Sorry, I don't have the privileges to turn them into hyperlinks.) The problem is, I'm not sure what the difference between the two files in the links above is. Is one of them more updated/recent than the other? Are both these versions unmodified and directly from Microsoft? It's difficult to tell since it seems MSDN doesn't provide any SHA-1 hashes for the latest Windows 8.1 Single Language available. I'd appreciate any help.
