Hey everyone! I'm reaching out to those who manage WSUS on completely isolated systems. I'm having some issues with my WSUS running on Windows Server 2022 (I've had the same problem with 2019 too) regarding the importation and application of updates to my network. Here's what I'm doing: I use another WSUS setup to retrieve update packages and run the command `wsusutil export C:tempexport.xml.gz`. Then, I import that file into the isolated WSUS with `wsusutil import C:tempexport.xml.gz`. The import seems to go fine, and I can see the updates in the console. However, when I check the updates under the Update tab, many of them remain stuck in a status saying 'The update is downloading.' When I check the file information for these updates and paste the URL in a browser from a user station, they download without issue. This has been a recurring problem, but it seems to be getting worse lately without any recent changes on my end, such as new GPOs. I've tried running `wsusutil /reset`, but that hasn't worked either. Has anyone else faced this issue and managed to find a solution? Thanks!

It sounds like you might be missing some updates. If a file is missing, it can cause WSUS to get stuck trying to download updates that theoretically should have all the right components. I suggest re-running the approvals and the sync on your source WSUS a couple of times. Also, make sure to check the 'definition updates'—those can often cause issues too.
Yeah, I get that it’s a bummer about the deprecation. WSUS is still the main free solution if you're working with isolated systems. Just bear in mind that updates for certain Microsoft products now come through other tools, like MECM. It’s a bit of a hassle to adapt, but it’s manageable.
Just a heads up, Microsoft has officially deprecated WSUS. They won’t be developing new features anymore. But don’t worry, it’s still a solid option for airgapped environments like yours. It's just that updates for Microsoft 365 and some other products aren’t handled via WSUS anymore, so there may be some new tools you'll have to look into in the future.
