How To Fix DSIM Error 50 On Windows 10 & 11?

To fix DSIM Error 50 on Windows 10 and Windows 11, follow these steps:

1. Ensure you're running Command Prompt as an administrator:

   • Press Win + R to open the Run dialog box.
   • Type cmd, then hold down Ctrl + Shift keys and press Enter. Confirm the User Account Control prompt.

2. Verify the command syntax: Make sure to include a single space between each parameter in the DISM command, like this:

   DISM.exe /Online /Cleanup-image /Restorehealth
   

3. Run the DISM command:

   DISM.exe /Online /Cleanup-image /Restorehealth
   

   This command scans and repairs the Windows image. It may take several minutes to complete.

4. If the DISM command is stuck or hangs, try the following:

   a. Wait for a longer period, as the process may take multiple hours to complete.

   b. If it still doesn't complete, try running the command again.

   c. If the issue persists, consider running the System File Checker (SFC) to repair system files:

   sfc /scannow
   

   This command scans and repairs system files.

5. If the issue remains, consider using the System Update Readiness Tool (KB29769358) for Windows 10 and Windows 11. Download it from the Microsoft Download Center or Microsoft Update Catalog, and then run it to resolve the issue.

6. If the problem persists, consider creating a system restore point and performing a clean Windows update or a clean installation of the latest Windows version if necessary.

Remember to create a system backup before attempting any advanced commands or updates.
