How to Free Up Space by Clearing “System Reserved” Files

by

If your SSD bar is red, your laptop will slow down significantly. In 2026, Windows updates and “Shadow Copies” can easily eat up 40–60GB of hidden space.

1. The “Storage Sense” Clean

Go to Settings > System > Storage. Turn on Storage Sense to automatically delete temporary files. Click on Cleanup Recommendations to find large “Windows.old” files from previous updates—deleting this can save 20GB+ instantly.

2. Clear the WinSxS Folder (Component Store)

This folder is vital but grows too large. Do not delete it manually!

  1. Open CMD as Admin.
  2. Type: Dism.exe /online /Cleanup-Image /StartComponentCleanup
  3. This safely removes older versions of system components that are no longer needed.
