Quote:Disk Cleanup is a useful tool integrated in Windows that users may run to delete temporary files and old data to free up storage space.
Microsoft revealed plans recently to deprecate the Disk Cleanup tool in favor of a similar feature integrated into the Settings app of the Windows 10 operating system.

The company expanded Disk Cleanup in Windows 10 version 1809, the October 2018 Update. The core change adds an option to Disk Cleanup to delete all files in the Downloads folder of the user.
