Why Are Windows 10 ESU Updates Showing in WSUS If We Didn't Pay for Them?

I'm noticing that Windows 10 ESU updates are appearing in our WSUS setup, but our organization hasn't purchased the extended support. Would deploying these updates actually work, or do they require some kind of license verification?

Just to add to that, it's really all about client-side enforcement. You can manually download those updates from the Microsoft Update Catalog if you want, or even snag them directly from the SoftwareDistributionDownload folder on a client that has ESU activated.

Yeah, this is actually pretty standard. WSUS will still show Windows 10 ESU updates even if your organization didn't buy ESU. But hereโ€™s the kicker: if you try to install them, they wonโ€™t actually go through unless the device has the ESU properly activated. You'll likely encounter a licensing error, or it just won't install at all. Microsoft makes these updates visible to everyone, but they check for ESU activation on the client side instead of in WSUS.
