Disk Cleanup

Updated: 06/21/2017 by Computer Hope

Microsoft Windows Disk CleanupDisk Cleanup is a Microsoft software utility first introduced with Windows 98 and included in all subsequent releases of Windows. It allows users to remove files that are no longer needed or that can be safely deleted. Removing unnecessary files, including temporary files, can help to speed up and improve the performance of the computer. Running Disk Cleanup at least once a month is an excellent maintenance task and frequency.

As can be seen in the picture, Disk Cleanup can delete Temporary Internet Files (associated with Internet Explorer), Downloaded Program Files, and Offline webpages. Disk Cleanup also allows you to empty the Recycle Bin, delete Temporary Files, and delete Thumbnails.

What to do in Disk Cleanup

Once Disk Cleanup opens, the initial window will ask you which drive you want to clean up. Select the appropriate drive and click OK. In the next window that opens, check each of the boxes you want to clean up. To the right of each item is the disk drive space each of the items are taking up on the hard drive.

Note: We highly recommend that users DO NOT check the option to Compress old files (if seen). Often this option causes more issues than the small amount of space it recovers is worth.

Once each of the boxes has been checked, click OK to start the cleanup process.
