Windows 10: Sysrq deactivation

Hello,

Today I wanted to take a printscreen of my laptop display but I accidentally pressed alt + sysrq. The screen told me to wait a while and then when the system came to its senses, all I could see was a black screen with a white panel on bottom and all the buttons and apps black traced with white. How do I put it back to it's original state as it was before? Please note two things: I'm an IT amateur, so I don't understand it much, and I'm not the admin of the laptop.

Thanks in advance for answers.

:)

 

PrtSc SysRq

I have been using the PrtSc SysRq for full screen screenshots. It is not convenient to use the snipping tool for this purpose. Why can't I do this any more?

Windows 10 Magic SysRq-like command

So I've got a MacBook Pro in a HengeDock, which prohibits access to the physical power button on the machine. I also use a few Thunderbolt devices to use the computer as a full desktop, and Windows doesn't support hot-plugging of Thunderbolt devices, so rebooting when it hangs normally goes something like

1. Pull MBP out of dock
   
2. Slam down device (Hold power button and wait until machine is off)
   
3. Reboot while holding option key, reboot into OS X
   
4. Put computer back into dock
   
5. Select Windows as startup disk in OS X
   
6. Reboot machine
   
7. Windows boots and is happy.
   

Now, that's a lot of steps - it usually takes me about 4 minutes to recover from a full hang, while being an entirely interactive process. However, if I reboot Windows straight away, no issues arise (i.e. start-power-restart, or even a full bluescreen crash - no problem.)

I know that the Linux kernel supports the "magic SysRq key" - which I have used and works just fine for this situation.

Is there a way that I could essentially do the SysRq + R/E/I/S/U/B type command on Windows? Or would it not work on a hung system?
