Summary:  How to use the Microsoft DISM Tool to Analyze and Clean the Windows 10 WinSxS folder (Component Store)

Comments:

  • DISM(Deployment Image Servicing and Management [DISM.exe]) is a command-line tool that can be used to analyze and clean up the Windows 10 Component Store
  • The Windows 10 WinSxS folder typically hosts all the Component Store files
  • Using the DISM command-line tool for analyzing the Windows 10 Component Store will show the following details of the components present in the WinSxS folder:
    • Actual size of the components in the WinSxS folder and also broken down into three sub-sections
        • How much of the actual size is shared with Windows 10
        • How much of the actual size is dedicated to Backups and Disabled features
        • How much of the actual size is used for Cache and Temporary Data
    • The number of reclaimable packages
    • Component Store Cleanup Recommendation (Yes or No)
  • Using the DISM command-line tool for cleaning up Windows 10 Component Store may recover some space of the hard drive(or SSD) and reduce the size of the WinSxS folder recovering a few GB’s of storage capacity.  Editor Note:  Normally Windows 10 will clean the Component Store when necessary thus clean up may not always be required, but if your system indicates otherwise(**After analysis**) follow the cleanup instructions below.

How To:

  • Using DISM’s /AnalyzeComponentStore
    • Open an Elevated Command Prompt => Press Windows key + X ] then select the ‘Command Prompt (Admin)’ option

(Note: The size of a component store can vary – normally about six(6) to ten(10) GB)
              • The analysis may take a few minutes. Do Not interrupt the process.
              • If your system indicates that Component Store Cleanup **IS** Recommended the DISM tool  /StartComponentCleanup command-line option can be used(instructions below)
