Some users are advising caution, but I don't see why this wouldn't work. If you want to check your key, there are dozens of softs (available from this forum) that can retrieve your key so you can write it down. Will try to do it myself (clean install, using UEFI key) as soon as I get all the LPs I want.
It's all depend on what Torrent Client you're using! I use MediaGet 2 because I like to download Music from the 50. - 70. and they having a lot of them in their Database. Many others as well and will downloading usin an working Magnet Link or via normal torrent Links! Just copy an Magnet Link and past it into the window you open by clicking the Folder Icon with the + inside. That's all and works great.
Thanks MrAnalysis for your guide for activation.... worked a treat on my surface pro.... only problem is that i have a watermark saying Windows 8.1 Pro, Secureboot isn't Configured correctly, build 9600... but im not to fussed by it!
OP says otherwise ? Code: Retail keys (including ProWMC upgrade keys), OEM: DM keys (Pre-installed windows 8 OEM), OEM:NONSLP keys activated users can upgrade & stay activated! Also a complete fresh install and re-activation should be possible. MAK of w8 does not activate. KMS of w8 does not activate 8.1
Quick one. To upgrade, we boot to OS and install that way? Boooting from Disc told me to do it this way
