I own an Alienare 15 R3 running Win 10 Enterprise.

Suddenly yesterday while using a bunch of shorcuts for a CAD program, accidentally my Windows key stopped working.

Found this topic locked :

but the solution offered :

https://support.microsoft.com/en-us/help/216893/how-to-enable-or-disable-the-keyboard-windows-key

is way to complicated.

So, with a little search, found the super fast solution to this issue.

Just press FN+6 to lock or unlock the Windows key !
