Windows Optimizer is an app for Windows 10 & 11 that applies many "fixes" (changes system settings) in order to maximize performance both for work and gaming especially.
I'm a gamer and applying all fixes in this app has made my games more stable (less/no frame-drops/lag-spikes) and has reduced my input lag and even increased my fps by a decent amount in most games!
This app also features some extra features that only apply to W11 such as the context-menu delay removal and restoration of the W10 context (right-click) menu!
It's free and open-source here so you can see exactly what the code does if you're cautious.
It also has an auto-updater that when you launch the app, it will compare the version to the latest and update, extract & overwrite & run the new, all of that is very fast (< 1 MB download).
