I have a test Lab running WSUS server and some VM's and a few Laptops. On the Laptops the updates seem to be stuck at 129 updates then just hangs at that point. If I reboot the Laptop it restores back. Any idea's?
Deploy 120 update in a round after that try to deploy only 10 more and check if the problem persist if that happen test 1 per 1 until you find the problematic one ignore it and deploy the others.
