# How to clean up the WinSxS folder in Windows 10 In Windows 10, you can save disk space by cleaning up or reducing the WinSxS folder. You can clean up the folder using DISM and Disk Cleanup. Note Do not delete the WinSxS folder under any circumstances! The folder contains important system files and shortcuts to Windows updates. If you get rid of it, you may no longer be able to start or update Windows 10 properly. ## How to clean up WinSxS in Windows 10 with DISM It’s important to be careful when cleaning up the folder. This should not be done manually. Instead, you can use the Windows 10 tool **DISM** (Deployment Image Servicing and Management). The instructions below describe how to use the tool to clean the WinSxS folder in Windows 10. ### Step 1: Open the command prompt as administrator To use DISM, you need to open Command Prompt. When opening Command Prompt, you need to open it as an administrator. If you do not have **admin rights**, you won’t be able to clean up the WinSxS folder. You can use the Windows 10 search function to open Command Prompt. Enter ‘CMD’ into the search bar and then click on **Run as administrator**.

This not only tells you how large the component memory currently is, but also when WinSxS was **last cleaned up** and whether a **cleanup** is recommended. Execute the following commands so that DISM can analyse the system folder: ```bash Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore ``` [![Image: DISM analysis of the WinSxS folder in Windows 10](https://www.ionos.com/en-ie/digitalguide/fileadmin/_processed_/3/8/csm_winsxs-dism-check_de9affa28f.webp "DISM analysis of the WinSxS folder in Windows 10")](https://www.ionos.com/en-ie/digitalguide/fileadmin/DigitalGuide/Screenshots_2024/winsxs-dism-check.png) The initial DISM check of the component memory will let you know whether it’s a good idea to clean up WinSxS. ### Step 3: Clean up WinSxS To clean up the WinSxS folder in Windows 10, execute the following CMD command: ```bash Dism.exe /Online /Cleanup-Image /spsuperseded ``` Files in the component memory that are outdated or no longer needed will be deleted from WinSxS. Provided your system is running stably and you are certain you no longer need any **older system versions**, you can also clean up all the Windows updates that are stored in WinSxS: ```bash Dism.exe /online /Cleanup-Image /StartComponentCleanup ``` ## How to reduce the size of WinSxS with Windows 10 Disk Cleanup If you find cleaning up the WinSxS component memory via command prompt too tedious or risky, **Disk Cleanup** is a great alternative. This Windows tool can be used within the familiar user interface to reduce the size of the WinSxS folder in Windows 10. ### Step 1: Open Disk Cleanup The easiest way to start Windows 10 Disk Cleanup is to use the Run dialog. You can use the key combination **\[Windows\]** + **\[R\]** to open it. Then enter ‘cleanmgr’ in the input field and click **OK**.

Note If you save your files in different locations, you will be asked which drive you want to clean before the disk cleanup begins. ### Step 2: Run the system scan Disk Cleanup will display temporary and unnecessary files that can be removed from your system. However, in order to reduce the size of the WinSxS folder in Windows 10, you need to be able to access the system files. Click on **Clean up system files** to start scanning these sensitive files (requires admin rights). Note The size of your WinSxS folder will affect how long it takes to perform the system scan and the deletion process. ### Step 3: Reduce the size of WinSxS After Windows 10 has been scanned by Disk Cleanup, the program will show you which files can be deleted. You can select various categories such as **Downloaded Program Files**, **Windows upgrade log files** or **Windows Update Cleanup**. The data in the categories you select will be deleted, **reducing the size of WinSxS**. Click on **OK** to remove the selected files from the system.
