Windows Server 2025 was once made usually to be had this week along System Center 2025. The corporate additionally launched a listing of validated processors and showed it’s an LTSC free up.

However, one can say it hasn’t been a clean touchdown, as with maximum different such Windows characteristic updates, since IT and device admins are already crying main foul as they to find that their programs are routinely being in-place upgraded to Windows Server 2025 from Server 2022.

The factor, weirdly, is being led to by means of KB5044284, which is the October Patch Tuesday replace for Windows 11, and no longer a Server free up, and there seems to be a case of flawed id as a Heimdal worker has defined on a Reddit publish.

After the problem was once known, Heimdal blocked KB5044284, and the company blamed Microsoft for the misclassification of the mentioned replace. The worker writes:

Andrei from Heimdal right here, guy, I’m truly sorry for the havoc that was once created with this replace, our workforce (thank you for elevating this with them – I’ve a sense you had been the primary to carry it as much as our Customer Success workforce) controlled to pinpoint this and blocked this replace throughout all server insurance policies to keep away from to any extent further upgrades from 2022 to 2025

..

Here’s the legit com. that simply went out some time in the past:
On fifth Nov 12.16UTC, Heimdal was once notified by means of a buyer about surprising upgrades associated with Windows Server 2025 of their setting. Due to the restricted preliminary footprint, figuring out the basis motive took a while. By 18:05 UTC, we traced the problem to the Windows Update API, the place Microsoft had mistakenly labelled the Windows Server 2025 improve as KB5044284.

Our Analysis and Fix:
Our workforce came upon this discrepancy in our patching repository, because the GUID for the Windows Server 2025 improve does no longer fit the standard entries for KB5044284 related to Windows 11. This seems to be an error on Microsoft’s aspect, affecting each the rate of free up and the classification of the replace. After cross-checking with Microsoft’s KB repository, we showed that the KB quantity certainly references Windows 11, no longer Windows Server 2025.

Currently, we will see that roughly 7% of our consumers had been impacted by means of this improve. To save you additional accidental upgrades, we’ve straight away blocked KB5044284 throughout all server team insurance policies.

It is noteworthy right here that Microsoft didn’t be offering any specific KB quantity for Windows Server 2025 free up, because it was once launched as construct 26100.1742.

For those that is probably not aware of it, Heimdal provides a Patch and Asset Management Module (AMM) for IT execs, by which updates will also be controlled and deployed by the use of Group Policy settings.

It is unclear in this day and age if different such AMMs are suffering from this too.
