Just ran disk cleanup. Windows update cache = 3.2 GB.

How the fuck can an OS updater have 3 fucking GB's of cache. God dammit do they put shit in just to mess with my already slow connection?

you know how big are windows WIMs?

Cached update files so you can share them within your network and spare your connection?

What this actually does is the same as DISM /Online /CleanupImage /StartComponentCleanup /ResetBase

If you don't want to search for it: it basically removes the option to uninstall Updates without a system restore.

This cache is functionally the same as the apt cache on Debian or Pacman cache on Arch
