I watch a Rerez video where he looks at force feedback flightsticks. These sticks came out around the year 2000, and use ports that modern PCs just don't have.
He tried plugging one made by microsoft into windows 11. This stick was made 26 years ago. It just worked. No setup. No drivers. Just, 26 year old stick.
The reason? They're still including drivers from Windows ME into Windows 11.
This is one very niche example, but the 300kb or whatever a driver size is, is being preinstalled in all windows 11 instalations. And Windows 10, and Windows 8, Windows 7, and Windows Vista, and Windows XP.
I'm gonna guess you can count on one hand the number of people using this flight stick on Windows 11. It only works with a handful of games, because it only ever worked on a handful of games.
Why would this be included by default on Vista or later?
Imagine how many thousands of other files are like this. Taking up space, without a reason.
