We have computers which were 1803 and have been upgraded to 1903 using SCCM to push out the upgrade using a service plan.
After this is deployed we are then deploying the update KB4524147 to the laptops using SCCM. The update will show as compliant in monitoring although it is not installed on the computer.
I then tried downloading the update manually from the online catalog online, but that didn't work either. The error message states that it is not applicable to the system. I tried different versions and am sure that I had the right one.
If I take a computer of the same make and model and install an image of 1903 (not an upgrade, but fresh install of Windows 10 1903) then I am able to download this very same update and install it.
It appears that the ones which were upgraded somehow are retaining information that makes it appear to be 1803 still to the update. Please can someone let me know where to start looking in order to troubleshoot this issue as I am stuck at this point?
