Remove Redundant Windows Versions If the Windows image contains multiple versions, we can reduce the size of the image by removing the extra versions.
Open install. Remove Redundant Windows Components Next, we need to remove the extra Windows components to further reduce the storage after the operating system is installed.
Test in VM I create two virtual machines with the original image and the new lite image, then compare their resource usage. Result We can see from the picture below that virtual machines created with the lite image take up less storage and use less memory at runtime. This is mainly because the system only contains the necessary system applications. Any changes you make to a mounted image are also applied to each potential target edition of Windows. Each target edition is staged in the image.
The changes will not be lost when you upgrade to a higher edition of Windows. You can use DISM to reduce the footprint of a Windows image by cleaning up superseded components, resetting the base of the superseeded components, and then exporting the image to a new image file.
Changes to applied images are saved, and you don't need to take any steps to commit the changes you've made. After you modify a mounted image, you must unmount it.
This makes your modifications a permanent part of the image. If you modified an applied image, you don't have to do anything else. You'll see any changes you made when you boot the PC. Open a command prompt or the Deployment and Imaging Tools Environment with administrator privileges. If you do not specify the parameters to unmount, this option lists all of the mounted images but does not perform the unmount action.
See Repair a Windows Image. If DISM processes are interrupted, consider temporarily disconnecting from the network and disabling virus protection. Skip to main content.
