To remove an update, use the command wusa /uninstall /kb:2982791 /quiet and replace the KB number with the number of the update that you want to remove.

It should actually delete the most recent update which would technically work

You can test this in cmd (user) do wmic qfe list brief and note the last installed update. Then do wmic qfe delete it will tell u in the output what KB it is - you'll notice it is the latest update. As the question relates to an immediate update using that command will roll it back

You can specify which update to delete using the wmic command. First, type wmic into cmd and press enter. You will then enter wmic You can type "qfe" on its own from here to view installed updates. type "qfe delete" wmic will show a KB to delete and ask for confirmation. If you dont want to delete this KB, type n. It will then run down to the next KB and ask if you want to delete. This will run through the currently installed updates so I believe this answer is "Yes"

I should note that running the command wmic wfe delete on its own will only attempt to uninstall the most recent update - so assuming the update that needs to be removed is the most recently installed, this will work.

Wmic qfe does have the Delete command: https://www.computerhope.com/wmic.htm However most other places suggest using the wusa /uninstall /kb command. With this command you can specify which update to delete. I guess the answer is "no", since we don't know if we want to delete the last update or if we have to specify which one

wmic qfe delete would delete the currently focused update which is the last one installed (standard). So my understanding is that this should work. Or am I getting the question wrong?
