Wsus not updating itself
When you approve that update, you’re gonna approve it for one or more different computer groups.
You can see here out of the box we have the all computers, and the unassigned computers groups here and then once those computers, at the client side, once they reach the next interval for checking in with WSUS, downloading and installing any updates, it’s then and only then that they’ll actually complete this process and get the updates downloaded and installed.
Obviously you’ve not approved any updates, so you should be seeing a long list of them.
Most of us are used to sort of pointing at a server and saying “You update yourself now”. Let’s talk about one more thing before we get our clients installed and that has to do with column here called installed as opposed to not applicable.
