After update KB5005565, my shared printers quit working on the client computer. I uninstalled the update, then they worked again. Now, after the latest update KB5006670, they quit working with different symptoms. The client computer can't connect to them over the network. The Microsoft online chat agent tried, but couldn't fix it. He told me, after over an hour's work, to just wait for the next update. Does Microsoft test these updates properly before they release them?
