Find areas of disk usage on Windows
The first step in investigating a disk usage issue is to find where the content is being used. This will allow you to remove unnecessary content (such as old backups) and make changes to prevent the issue from recurring. Windows users have a many options to investigate disk usage. We like to use WinDirStat because it uses very little disk space while providing a helpful breakdown of usage.

- At startup, select the drive to examine, or All Local Drives.
- After the scan completes, you can expand directories in the results view the paths to find large files and folders:
- From your desktop, open Windows Explorer and remove any unwanted content.

Note: If cleanmgr.exe is not available, it may need to be installed. It is not installed by default on Windows Server 2012 or earlier. You can enable the utility by installing the Windows Desktop Experience through the Server Manager. Installation instructions can be found here.
After clearing disk space, it's a good idea to reboot the server to make sure all needed services are properly restarted.
