That's a tough question and I don't really have am answer.
But if it's work related I'd look into finding a Windows SysAdmin course somewhere and ask my employer to pay for it, since it helps with your work.
A cheaper alternative would be online courses. I found Udemy quite helpful in that regard.
Another possibility is Microsoft Learn, which offers basic to professional "Learning paths" you can do on your own time. There's also a SysAdmin certification available if I recall correctly.
Edit, since I just reread your post: Microsoft Learn is almost completely about Azure. So you should really take a look at it.
It's amazing they didn't implement something like that if it actually is soooooo costly.
No wonder they want an AGI if they have trouble thinking themselves.
