Run Disk Cleanup to Remove Temporary Files in Windows 8

The Disk Cleanup utility, included with Windows, is a useful application to run frequently, as it removes temporary Internet files, empties the Recycle Bin, removes dump files generated when an error occurs, removes backup files generated when Windows installs a Service Pack, and miscellaneous other temporary files that Windows doesn’t go into detail about.

Disk Cleanup works the exact same way in Windows 8 as in previous versions, but finding it is a little trickier.

Running Disk Cleanup

To run Disk Cleanup:

  1. Press the Windows Key to go to the Start Screen
  2. Open the Charms Bar
  3. Click Search
  4. Type cleanmgr in the box
  5. Click the cleanmgr icon

  6. Disk Cleanup
    Click the icon after it comes up in the search.

  7. You’ll be asked to select a drive.

  8. Disk Cleanup
    Select a hard drive where you’d like to clean temporary files.

  9. Then, after Windows calculates how much space you’ll save, you’ll see a list of options. Select one or more of them and click OK.

Scroll down to see all the temporary files you can remove.

Choosing Temp Files to Delete

Though only a few items are checked by default, feel free to check more of them. Please note, however, that once the files are deleted, they’re gone forever. The good news is that there’s almost no situation where you’ll need any of these temporary files. Here’s one exception to take note of: If you’re on the phone with Microsoft Support immediately following an error, they may need to see the error log files. If you’re at all concerned about that, leave that option unchecked.

This cleanup process will take several minutes, and then you’ll be able to take advantage of the free space immediately.
More precious space on your hard drive is always better. Windows uses free space on your drive as temporary RAM, called virtual memory. Plus, you want space on the drive for more important things, like new applications, videos, photos and music. You can gain back gigabytes of space using Disk Cleanup. Try it out.

    What would happen if i delete thumbnails

  • ReviverSoft

    Hi Nehemia,
    Deleting thumbnails means you won’t see an image preview in a Windows folder. You may want to keep these around.

    Thanks very much, Kuldip!

    Usually nothing. We go into the pros and cons of deleting certain types of temp files in the article itself. Good luck!

    Windows 8.1 apparently fixes this issue, as I see cleanmgr just fine when performing a search from the Start Screen.

  • Así que parece que usted está teniendo un problema con las fuentes que no aparecen? Me gustaría desinstalar las aplicaciones que ha instalado para administrar las fuentes y en lugar de tratar de conseguir fuentes directamente desde Microsoft.

    if you’re using a start menu replacer (I recommend vi start by lee soft) in the search bar on it (in desktop mode) type cleanmgr. Or anywhere you can use the run box.
