Hi,

You can do this by executing powershell command.


For example:

Using dism command you can find a package which is relied to proper KB:

|dism.exe /online /get-packages /format:table |

or powershell command:

Get-WindowsPackage -Online |ft -Autosize


Note that dism command doesn't always show full KB name (or I don't know
how to force it to show it), but result can filtered by install date.
Using powershell command (I think it's better than dism) you will get a
result with all updates formatted like this:

Package_for_KB5015684~31bf3856ad364e35~x86~~19041.1799.1.2                                          
 Installed         Update 26.05.2023 12:28:00



If you know package id, you can check it by using powershell command, to
be sure, you are going to uninstall proper KB:

|Get-WindowsPackage -Online -PackageName '*19041.1799.1.2*' |

This command will give you a result similar to this:

||

|PackageName :

And if you are sure about KB (here we have KB5015684), you can uninstall
it non-interactively:

|Get-WindowsPackage -Online -PackageName '*19041.1799.1.2*'
|Remove-WindowsPackage -Online -Verbose|


You can run this command from batch script:

|powershell -noninteractive -Command "Get-WindowsPackage -Online
-PackageName '*19041.1799.1.2*' |Remove-WindowsPackage -Online -Verbose"|


I hope it helps you.
