|Some Systems have been not able to substitute the Microsoft Edge browser with The chromium version of the same browser. They have removed the browser but not installed the later. This problem occurred on the PC having Windows installations created from either custom ISO image or custom offline media. This issue is only confronted when ISO images or custom offline media are created by slipstreaming this patch into the image without having first installed the SSU dated 29/03/2021 or later.|
Remark – Computers that connect straight to Windows Update to obtain updates don’t face any problem. This also includes systems powered with Windows Update for Business. Worth remembrance is any system connecting to Windows Update should always obtain the latest SSU and without any extra steps.
|Trying to stay away from this, then first of all slipstream the SSU dated 29/03/2021 or later into either ISO image or custom offline media Subsequently, slipstream the LCU. In order to do this with the combined SSU and LCU packages now used for Windows 10, v20H2, and Windows 10, v2004, you will need to extract the SSU from the combined package. Pursue the steps to extract the using SSU –|
1. Unpack the cab from the msu through this command line (using the package for KB5009543 as an example): expand Windows10.0- KB5009543-x64.msu /f:Windows10.0- KB5009543-x64.cab <destination path>
2. Unpack the SSU from the previously extracted cab via this command line: expand Windows10.0- KB5009543-x64.cab /f:* <destination path>
3. You will then have the SSU cab, in this example named SSU- 19044.1466-x64.cab. Slipstream this file into your offline image first, followed by the LCU.
