Microsoft admits latest Windows 11 update is breaking some VPNs

[[{“value”:”

Windows 11 and Windows 10 users are in some cases facing a problem whereby their VPN connection is failing to work thanks to the latest cumulative updates from Microsoft for these operating systems.

We’re talking about the main updates for last month, April, which are KB5036893 for Windows 11 (ushering in Moment 5 features), and KB5036892 for Windows 10 – and this also holds true for the preview updates released at the end of April.

Neowin noticed that Microsoft has officially acknowledged that these updates are breaking some VPNs, posting on its Windows 11 health dashboard to say: “Windows devices might face VPN connection failures after installing the April 2024 security update (KB5036893) or the April 2024 non-security preview update.”

Microsoft informs us that it’s working on fixing the problem and will “provide an update in an upcoming release,” but sadly, we don’t get any details beyond that.

Analysis: Rocky road for updates of late

This is a vague diagnosis from Microsoft, with no info provided as to what might be the root cause (or causes) of this VPN-related problem. It’s not affecting all Windows 11 (or Windows 10) users by any means, but certainly some VPN users are experiencing service failure. All we can do right now is wait for Microsoft to continue its investigation into finding out what’s gone wrong with the April update, and to provide those additional details – hopefully soon.

For those affected, this is a troubling situation, as the April cumulative update is very different from an optional update – you have to install it (Windows 11 Home users can only delay it for a bit if they want to take evasive action). Also, without the update, you don’t have the latest security measures, so your PC is just a bit more vulnerable to intrusion.

For home-based PC users running into this bug, Microsoft only offers up the following advice: “If you need support with your personal or family account, use the Get help app in Windows.”

It’s been a pretty rocky road for the April update for Windows 11 when you consider that the upgrade has brought with it some other nasty bugs, including a new spin on the Blue Screen of Death – which we dubbed the White Screen of Doom. Plus the preview update for April has an odd issue with profile photos, and there are other glitches floating around besides. So, all in all, Microsoft isn’t having a great time of things lately.
