Disk Cleanup scans and calculates how much space you will be able to free on that drive:


If you scroll through the files to delete, you’ll see the new option added by this update along with the amount of space you can save. It’s called Windows Update Cleanup. Notice it is checked by default?

When you click ok, Disk Cleanup runs and cleans up the unnecessary files on your machine. You can see it running the Windows Update Cleanup as part of this below:


Disk Cleanup finishes and exits.

You will need to restart the computer for the space to be freed up.
