A recent post in AskWoody reminded me of a utility I came across a while back.
The AskWoody article refers to the Winaero utility Winaero Tweaker. You can download it here.

Winaero Tweaker makes that literally a one-click operation. Here's their write-up on it.
If that's not geeky enough for you, just scroll down and read the comments. Follow them at your own risk.
