Bonus: If you use the new TSForge method, it's a permanent hardware registration. Meaning you'll never have to activate Windows again, just connect to the internet and it'll do it's thing when it calls home.

It also has ESU support for Windows 10, so you can register for the extended security updates after it reaches EOL completely free.

Oh, in that case, I assume they have you running Pro or Enterprise? If so, ignore what I said about disabling the Remote Desktop and Work Folder stuff. Work Folders especially though, they're a complete pain (or were) and used pretty frequently. So you'll probably be working with them a bit.

I bought a cd key for like £4 from one of those dubious cd key sites. It worked flawlessly. I don't know how legal that is exactly (the internet isn't exactly clear on how those sites obtain keys), but tbh it's good enough for me and has no risk of malware. I figure Microsoft could easily block such keys if they wanted and they haven't.
