How to: Windows Administrative Tools for Power Users

When I had first installed Windows 8, I found that one of the most frustrating things was the lack of easy access to anything that was power-user-administrative-like.
After installing Windows 8, I found myself clicking the mouse 4-6 times to access these tools.
Granted, you have the Search in the Charm Bar, but that still was not as fast or easy as it should be.
Then I discovered the Number 1 most powerful Windows 8 shortcut for the Power User.
It's Windows Key+X.

Here you can access easily System Information, Device Manager, Power Options and even the Task Manager!
