Remove Superseded and Unused System Files with DISM (Standard 8)
7/8/2014
Learn how to remove superseded and unused system files from your Windows Embedded 8 Standard (Standard 8) image by using Deployment Image Servicing and Management (DISM).
In Windows Embedded 8 Standard (Standard 8), you can choose to remove superseded or unused system files to help prevent the size of your image from increasing over time. Part of this increase can result from servicing files remaining on the system after installation, previous updates remaining on the system, and from unused system files. Deployment Image Servicing and Management (DISM) scavenges the contents of the Windows store. You can clean up your image by using the Disk Cleanup utility or by running the following DISM command:Dism /Online /Cleanup-Image /StartComponentCleanup
Prerequisites
- You have access to either a device currently running Standard 8 or to a Windows image (.wim) file that contains the Standard 8 image that you want to update.
- You have installed Windows Embedded 8 Standard Toolkit (Standard 8 Toolkit) on a development computer.
