If your software is in support you are fine.
That's not the issue. The issue is the fact that this supported software is breaking things badly. Great, there's a problem, ask Microsoft for help.
It sure helped
here. Not.
Microsoft needs to do a better job releasing Patch Tuesday updates that don't cause major problems. Pretty much every Patch Tuesday release breaks something important for someone. Not everything, not everyone, not all at once. But Microsoft simply isn't spending enough effort testing things before release.
THAT is why I wait a couple of weeks before installing Patch Tuesday updates. At my last corporate job, the IT department would install Patch Tuesday updates on test systems and try them out with the company's most used applications BEFORE pushing out the Patch Tuesday updates to employees (which often happened on the weekend following Patch Tuesday).
Because troubleshooting Microsoft's f-ups is
A BIG WASTE OF TIME. No one wants that, even if they have support. Support is not the issue. The time wasted on Microsoft's incompetence is the issue. And inconvenience to people who did nothing wrong on their own like employees who rely on their IT staff to install updates.
But a lot of users here are using builds with support dropped or resisting updates. There's the rub.
That makes zero sense. This topic is about a broken Patch Tuesday update that is borking VPN, an important tool used in the corporate world. KB5036893 cannot be installed on unsupported builds. And those who resist updates wouldn't have the problem (just more security vulnerabilities, but at least they can use their VPNs).
And no one can tell just by looking at someone's TPU handle that they are using an unsupported build of Windows.
Whenever I fire up a Windows box, regardless of whether or not it's on my time or on a work clock, there is no benefit for me throwing away my time trying to dig myself out of Microsoft's cesspool. I didn't boot my Windows system to deal with this crap. I booted it to write some e-mails, maybe look at a spreadsheet. Or maybe look at cat videos and play Fortnite. Support or not, KB failures does not help be do any of these things.
Worse, it just erodes user confidence in Microsoft even if the particular failure doesn't affect you directly. It's like a school shooting. Even if no bullets hit you, there's damage done anyhow. That's a rather extreme analogy but Microsoft does not come out ahead if only 30% are affected by snafu versus 35%. It's the continual loss of trust.
Trust is earned and Microsoft is squandering far faster than they are earning it these days.
