Bring up your clipboard history:
We all know the Ctrl-V shortcut for pasting the most recent item we’ve cut or copied. But what if you need to paste something from hours ago?
Clipboard History comes to the rescue by storing up to 25 of your most recent cuts or copies. If you have a piece of text or data that you use frequently, you can pin it to the list by clicking the Pushpin icon next to the entry. Pinned items will remain in your Clipboard History, even after logging out or restarting your computer. 
For all PC users:
Press Windows + V To access your Clipboard History.
Before that don’t forget to turn on clipboard history from the setting. 
Hide or unhide the desktop:
If you’re working on something private and need to quickly hide all open windows when someone approaches, you can press Win-D. This will instantly minimize every window. Pressing Win-D again will restore all the minimized windows to their original positions.

For all PC users:
Press Windows + D
To quickly hide and unhide open windows on your desktop.
