Server issues with KB4534271

I am having a challenge with an update for Server 2016 Standard.  My network is small with one Hyper V hosting two instances of server 2016 Standard.  Svr1 and Svr2.  Svr1 is the domain controller, DHCP DNS server.  Svr2 hosts one program.
The issue started with being advised updates were available.


Svr1 is downloading updates, and has been at 11% for over 2 hours.

 Svr2 is downloading something and was at 31% 18 hours ago.  When I try check on Svr2 to see if it has advanced, Settings will not start.  The CPU shows 99 to 100% from task manager,  Svr2 has Service Host:Local (17) using the 99 to 100%
I have tried to end task for Windows update and Update orchestrator service on Svr2..  Both are listed as stopping in Services  , but do not actually stop.

Svr1 shows System to be using 94 to 95% CPU resources.

Is there a method to either stop the update process, or assist it in some manner to free up server CPU resources?  Is there a better way to get this update than letting Windows attempt to download it.  The internet speed is not great at this site  [3 to 5 Mbps down, 1 Mbps up]

all the best
interrupting updates is usually not recommended. and applying updates automatically or manually on both dcs at once is clearly an error as you probably noticed by now. and you need to snapshot before such operations as well.

i would suggest using a tool such as filemon, and/or procexp to try and see what the process does so you can determine wether it is looping in circles or actually doing something and possibly guess how long the operation will take. since both servers reached different stages and the percentage grows, you probably should be patient.

it might be sensible to fire a backup or clone a dc from a snapshot of srv1 in the mean time if you have a reasonably recent one. if you do so, beware the ids are the same so you cannot fire the real server at the same time without making a mess. also be careful which way the replication will go when srv2 will be done with the update. personally i would refrain from doing any domain related operation, and stop the clone before starting srv2 just to be on the safe side.

I over reacted, and SVR1 had completed and wanted a restart, which is happening now.  SVR2 has two failed updates I will deal with later, after making the snapshot
