Reserved Storage is a portion of storage space which is used by Windows 11 to save temporary files for system processes like Windows Update, so you’ll no longer experience Windows Update issue because of low disk space.

2. Click the “Show more categories” link.

2. It will give you the details of each reserved space. Just add the sizes of each Space Guarantee and you can find out how much disk space is allocated for reserved storage.
