|Sadly the built-in web browser is removed but not replaced from some of the devices. This happens on the system which uses either custom ISO image or custom offline media for installation.||To keep away from this problem, don’t forget to first slipstream the 20/03/2021 Servicing Stack Update or later into the custom offline media or ISO image before slipstreaming the Latest Cumulative Update. In order to perform this with the combination of LCU and SSU for Windows 10 v2204 and v20H2, you will have to unpack the SSU. Follow the steps –
Unpack the cab from the .MSU through this command line (using the package for KB5007253 as an example): expand Windows10.0-KB5007253-x64.msu /f:Windows10.0-KB5007253-x64.cab <destination path>
Now unpack the SSU from the above-extracted cab using: expand Windows10.0-KB5007253-x64.cab /f:* <destination path>
3. You will then have the SSU cab, in this example named SSU-19041.1387-x64.cab. Slipstream this file into your offline image first, then the LCU.
