I‘m fine, just a lot of work due to COVID-19...
I can take a look at the list of updates and check them, but expect me to be very slow.
I don’t see any reason in installing a more recent servicing stack than 01/2020 as the only change I know about is allowing the next ESU-update to be installed. To prevent incompatibilities and/or strange behaviour (as wsusscn2.cab still lists the Servicing stack from 01/2020), I‘d keep it as it is.
