only the latest of the updates above would install. Said something to the effect of “this update does not apply to your system”. I double checked that I :
1 : am on 1909
2 : selected the 1909 and not 1903 update
3 : selected the x64 and not the ARM64 update
I am now on 18363.778
I am about to turn the scanning back down to 1 hour and will reset server to get fresh logs.
Thanks.
