It is long story I don't know what I did wrong or what went wrong, so please help me out fixing this mess So I downloaded ESD from tb.rg-adguard.net ESD > Win10 v1709 Redstone 3 December 2017 > Windows 10 Consumer > EN-GB > 16299.125.171213-1220.rs3 and used gus33000-ESD-Decrypter for conversation into .iso then used portable rufus and build a bootable usb. During installation I found only two options Windows 10 S & Windows 10 S N So I installed S till that time I didn't knew what the hell is S. So right now I am stuck with Windows S on my new laptop, I tried to upgrade to Pro using keys which I found googling but it didn't work. It doesn't even let me Install 7z. I want to upgrade to pro. So how to? Do I need to re download, re decrypt, re unmount, re Install (I don't want to waste this much time) What are possible ways. And how to activate?
