How to get free disk space back after installing Windows 8.1 Spring Update 1 (Feature Pack)

Yesterday I installed the recently leaked RTM build of Windows 8.1 Spring Update 1 (Feature Pack) and was disappointed by the fact that my free space was considerably reduced after installing it. You may face a similar scenario and may not be able to reclaim all the disk space again just by running Disk Cleanup or CCleaner. So in this article, I would like to share with you a simple way of cleaning unneeded files from your hard drive after installing the latest Windows 8.1 updates.

My disk free space got reduced by approximately 7 GB. Windows 8.1 does not come with any special cleaning tool to do comprehensive cleanup, so I tried the built-in cleanmgr.exe tool (Disk Cleanup). It cleaned up approximately 900MB after doing Windows Update Cleanup so I was determined to get more free space back. Here's what I did:

  1. Open a command prompt as administrator (see how).
  2. Type the following command:
    Dism.exe /Online /Cleanup-Image /StartComponentCleanup /ResetBase

  3. Delete all of the files from C:\Windows\SoftwareDistribution\Download folder. (They are files stored by Windows Update before updates are installed. After any update is installed, it is safe to clean up this folder).
  4. Reboot your PC

This can free up several GBs of disk space. This is similar to the way you clean up disk space after installing updates for Windows 7 but does a more comprehensive cleanup. The only downside to this is that you won't be able to uninstall the updates.

    elevated permissions are required to run DISM. Use an elevated command prompt to complete these tasks.
