This guide will show you easy ways to check the Reserved storage on your Windows 11 computer using simple tools like the Settings app and the Command Prompt.

What is Reserved Storage?
Reserved storage is a special space on your computer’s hard drive that Windows keeps aside just for important things like system updates, apps, temporary files, and system caches. This helps your computer run smoothly, especially when your disk is running low on space.

Usually, Windows sets aside about 7 GB for reserved storage, but this size can change depending on your computer and how much free space you have.

Checking your reserved storage helps you understand how much room is left for your personal files and programs. It can also help you figure out if low disk space is causing your computer to slow down.
