How to Upgrade to Windows 11 Using DISM: A Tech-Savvy Approach


Are you considering upgrading to Windows 11 but looking for an alternative to the standard update methods? The Deployment Image Servicing and Management (DISM) tool offers a more technical route, which might be perfect for advanced users and IT professionals. Here’s a concise guide on how to use DISM to upgrade to Windows 11.

Step 1: Get the Windows 11 ISO
Start by downloading the official Windows 11 ISO file from Microsoft’s website. This file contains the installation data needed for the upgrade.

Step 2: Mount the ISO
Once downloaded, right-click on the ISO file and select “Mount”. This creates a virtual drive, simulating a physical disc in your computer.

Step 3: Open Command Prompt as Administrator
To run DISM, you need administrative privileges. Search for “Command Prompt” in the Start menu, right-click it, and choose “Run as administrator”.

Step 4: Apply the Image Using DISM
In the Command Prompt, input the following commands:

  1. Check and repair system health:
   DISM /Online /Cleanup-Image /RestoreHealth
  1. Locate the Windows image:
   DISM /Get-WimInfo /WimFile:<DriveLetter>:\sources\install.wim
  1. Apply the Windows 11 image:
   DISM /Online /Apply-Image /ImageFile:<DriveLetter>:\sources\install.esd /Index:1 /ApplyDir:<YourInstallPartition>:\

Replace <DriveLetter> with your mounted drive and <YourInstallPartition> typically with C:.

Step 5: Complete the Upgrade
After the DISM process completes, restart your computer. Follow any on-screen instructions to finalize the upgrade.

Important Notes:

  • Backup: Always back up important data before upgrading.
  • Compatibility: Ensure your device meets Windows 11 requirements.
  • Risks: Using DISM is complex and can cause system issues if done incorrectly.
  • Seek Help if Needed: If unsure, consult a professional.

Upgrading to Windows 11 using DISM is not for the faint-hearted but offers an interesting alternative for those who prefer a hands-on approach. Happy upgrading!
