A software utility first introduced with Microsoft Windows 98 and included in all future releases of Microsoft Windows that enables users to remove files that are no longer needed or that can be safely deleted.
As can be seen in the picture to the right, Disk Cleanup can delete Temporary Internet Files (associated with Internet Explorer), old downloaded program files, empty the Recycle Bin, and delete Temporary Files. Newer versions of Disk Cleanup (e.g. Windows XP and later) also allow users to delete Offline Webpages, Microsoft Error Reporting Temporary Files, WebClient/Publisher Temporary Files, Compress old files and Catalog files for the Content Indexer.
How to open Microsoft Disk Cleanup
Microsoft Disk Cleanup can be opened by following one of the below methods.
- Programs, Accessories, System Tools
- In System Tools click Disk Cleanup
- Start, Run
- In the Run line, type cleanmgr
- Open My Computer
- Right-click the drive you wish to run Disk Cleanup on (e.g. C: drive)

What to do in Disk Cleanup
Once Disk Cleanup is open check each of the boxes you wish to run. To the right of each option is the disk drive space each of the items are taking on your hard drive.
Note: We highly recommend that users DO NOT check the option to Compress old files. 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.
