Obviously this isn’t terribly useful, which is exactly what makes it a Stupid Geek Trick. Either way, it’s a good learning experience to better understand how your OS works.
Adding the Windows Version to the Desktop
The trick is really simple, you just have to edit a key in the registry and you are done. Let’s start by opening the “Start Menu”, type “regedit” then hit Enter.
When the Registry window open, from the left pane, navigate to this key:
Make sure you select “Desktop” and not the subfolders in it, then on the right-hand side, search for “PaintDesktopVersion” and double-click it.
(The registry entry’s data will be “0” by default. In the screenshot below, we’ve already changed it to “1”.)
A dialog will pop-up, change the “Value Data” field to 1.
Now restart and you’ll see your Windows version printed on the desktop. It’s pointless but interesting.
If you want to remove the watermark, just change the “Value Data” field back to 0 for disabled.
