How to Disable Disk Cleanup

By Samuel Wade

Windows Disk Cleanup is a built-in tool to help reclaim disk space. Under certain circumstances, however, it can nag the user and become an irritation. This may happen when disk space is critically low, in which case the notification can be disabled. Alternatively, the system may be running the application automatically at scheduled intervals. In this case, the task can be deleted.

Things You'll Need

  • Windows PC
