How do I upgrade a Windows 8 machine without a network connection to Windows 8.1?

2You should be able to use go.microsoft.com/fwlink/p/?LinkId=271128 and the key contained in the accepted answer to this questionr: superuser.com/questions/661261/windows-8-1-fresh- install-with-windows-8-licence in order to do this. After your upgrade is finished you will have to change the license back to your Windows 8 installation described by the accepted answer here superuser.com/questions/650019/… When I can provide an answer that isn't all links I will post an answer.– RamhoundOct 17, 2013 at 17:42

I don't think any of you have noticed that using the ISO, we lose all non-metro-applications. It's just as if we did a refresh: we have to reinstall all non-metro-apps afterwards. Yes, I tried it, only metro-apps survive this type of upgrade. There is no way shown to upgrade it offline and achieve the same as with the online upgrade. While on my first 2 win8 pro it did not work (as described before), on the other 4 it worked. A little irritating, yes. All actions were the same. So I assume, the upgrade procedure is not 100% stable.– HagenOct 28, 2013 at 20:54

Download a Windows 8.1 ISO (when you have access to it via MSDN/Technet), mount it inside Windows, run the setup.exe
and select "upgrade".

Issue with this to be aware of that MSDN/technet is not meant for production. MSDN is for development & TechNet is for testing. So if you have a retail key, it isn't the supported methods for this. Dec 23, 2013 at 20:51
