Life-saving keyboard shortcuts that will make your life better now that you know them. Windows-only. If you're a Mac user, go away. 1. ALT + SPACE + N = Minimizes the currently active window. 2. WINDOWS + M = Minimizes all windows. Or, you can also use WINDOWS + D to minimize/restore all windows. 3. ALT + PRINT SCREEN = Screenshot of the current window. ( <— Woohoo! ) 4. CTRL + TAB = Switches between windows in the current application. 5. CTRL + F6 = Same as above, except that the above sequence acts like an ALT+TAB for the application whereas this one just goes to the next active window. 6. WINDOWS + E = Opens Windows Explorer. 7. WINDOWS + L = Locks the computer. 8. WINDOWS + BREAK = Opens System Properties. 9. WINDOWS + CTRL + F = Opens computer search. 10. WINDOWS + R = Opens run.

There are also the well-known ( one hopes ) CTRL+C (copy), CTRL+V (paste), CTRL + X (CUT), CTRL+W (close active window), ALT+F4(close active application) that I couldn't possibly live without.
