The article here addresses the issue how to get rid of a specific KB (Update) and shows some more DISM commands to fix broken Windows online images. With a few tricks in the Windows Deployment Image Servicing and Management command utility, admins can solve some of the most common Windows 10 update problems plaguing their users.
DISM is really powerful and is well documented in the official Microsoft docs, which you can find right here. There is an unofficial GUI utility for it in case you’re not really a friend of the command line which is called DISM++ developed by a Chinese guy since several years but it’s not really needed because the command line parameters are very easy to understand and as already mentioned, well documented,
Identify the installed cumulative updates (KB)
First, we need to find the list of packages installed on the PC with the issue by performing this command
- dism /online /get-packages /format:table
Alternative you can use this to get a better view
- dism /online /get-packages /format:table > patches.txt
This will generate a list called ‘patches.txt’ were you can see all installed updates or hotfixes.
Remove the problematically KB
Let’s say you want to remove the Package_for_KB2870699~31bf3856ad364e35~amd64~~6.2.1.1 package, then use the following command to silently remove it:
- DISM.exe /Online /Remove-Package /PackageName:Package_for_KB2870699~31bf3856ad364e35~amd64~~6.2.1.1 /quiet /norestart
You could use this command in a batch script in case you want to remove more than one update, the hardest process is to find the exact name but with the given method you just need to look at KB number to identify which package you need to remove. If you want to get rid of a hotfix this is a little bit more complicated because there is no specific identification given and the names are random, so before you install a hotfix, ensure you make a list of the currently installed updates and compare it against the list after you installed the hotfix.
