I hava an oem license of windows 8 core & I want to upgrade to 8.1 . Since my internet connection isn't reliable it's hard to get the update from windows store app. So I'd like to download an iso of windows 8.1 which is unofficially availabale. After I do the installation(with a generic key,if required) will I be able to activate with my windows 8 product key?

Installing or upgrading to Windows 8.1 via ISO requires you to mount ISO files or boot from bootable disc. Ensure your Windows 8 device is power connected. I found a full tutorial on Upgrading Windows 8 to Windows 8.1 using ISO here
