問題 · PROBLEM
Why is my Windows storage full?
You did not install a new game. You did not download a 4K movie. So why does Windows say you are out of space? The answer is usually a mix of Windows Update remnants, old restore points, hidden caches, and downloads you forgot about.
Windows Update cache Old restore points Downloaded installers
