Windows 10 ADMINISTRATION is blocking me doing many things on my LENOVO THINKPAD YOGA 12.5 INCH laptop?

I want to download apps such as Steam and Skype, so when I try, I get asked to provide admin details (username and password), so when I do, I get told that it requires evaluation, I can't really remember the message, WAIT I'VE GOT IT, IT WAS 'Operation requires evaluation'. So yeah, just wondering. PS: I believe that as this is a loan laptop from my school, they may have blocked some apps?

Of course they have to protect THEIR machine and network from idiots.
