How often do you reinstall Windows 11?

I've had mine for about two and a half years now. It started getting pretty slow at startup, so I finally bit the bullet and did a complete reinstall from a USB stick—wiped the main drive and started fresh.

Definitely feels snappier now.

Over the years, I've swapped GPUs a couple times—Nvidia to AMD and back to Nvidia—and installed/uninstalled countless apps. Pretty sure all that clutter was taking a toll on performance.

Just curious—how often do you guys reinstall? Once a year? Every few years? Or do you just deal with the slowdown until it becomes unbearable?
