10 Incredibly Useful Keyboard Shortcuts for Windows
Quickly open 'My Computer': Windows Key+E
This handy shortcut gives you quick access to your hard-disks, CD and DVD drives, and any other devices which are currently connected to your PC. This is really the gateway to your PC, and from here you can navigate to pretty much any important files you might need, and a whole lot more.
Switch between windows quickly: Alt+Tab
Note: Tab is usually the button to the left of the 'Q' on your keyboard
How many times do you find yourself needing to switch back and forth between programs, grappling with your mouse to hit the minimize button, search for the program you want in the toolbar at the bottom of the screen, over and over? Have you ever thought, "there must be a better way."? Well, there is. Hit Alt+Tab to show a quick summary of all the currently open programs. Let go of the Tab button (but keep pressing Alt) and then hit the Tab over and over to cycle through the different programs. Once you let go of both Alt and Tab the program you've highlighted will pop up.
