This tutorial will show you how to turn on or off Storage Sense to automatically free up system drive space for your account in Windows 11.
Storage Sense can automatically free up drive space for you by getting rid of items that you don't need, like temporary files and items in your Recycle Bin.
Storage Sense is off by default. If your PC runs into low disk space and you have not interacted with Storage Sense in the past, Windows may turn on Storage Sense to manage select temporary files, then notify you. If you prefer, you can choose to turn Storage Sense off right away or after the low disk state is resolved.
If Storage Sense is turned on with the default settings, it will run when your device is low on disk space and will clean up unnecessary temporary files. Content from the Recycle Bin will be deleted by default after some time, but items in your Downloads folder and OneDrive (or any other cloud provider) will not be touched unless you set up Storage Sense to do so.
Starting with Windows 11 build 22557, Storage Sense will now be enabled by default for PCs going through OOBE. Your current settings will be persisted on upgrade.
