Cumulative Updates - February 27, 2020 - KB4535996 Optional

I am replying to this comment as it is the final one in the thread.

Wanted to add my own experiences with this update.

I have been getting very high latency in the ndis.sys driver since updating, to the point where audio is stuttering so badly it is unusable.

Disabling the wifi adapter stops this (as it stops ndis.sys working).

I have found through latency monitoring, that this issue presents itself most commonly on start up, and then if the wifi adapter is turned off, then on again around 3 or 4 times, slowly, for a few minutes, the ndis.sys driver stabilises and remains stable for hours on end.

Weird, and definitely 100% started when the update processed on my system.

Yes, if someone is presenting a misdiagnosis of their issues it could be an update issue, but there's no reason to say that the bugs are inaccurately reported to make it fit a narrative. I'd love to just fix this guy's PC for him, free if it's because of the update.

Different article, one by techradar. Sorry for the ambiguity.

If it were 1 or a few people's computers, you would be correct.

But with so many people having a lot of similar/same issues on different HW/BIOS & right after KB4532693 & KB4524244 were installed, it is no coincidence.

Microsoft has admitted these 2 KBs are causing serious issues: pulling KB4524244 & admitting KB4532693 has a "critical bug".

"Pushed to users as part of its latest ‘Patch Tuesday’ updates, Microsoft has confirmed the KB4524244 security update bundled in it can cause system freezes and crashes across every supported version of Windows 10, from Windows 10 Home right through to Enterprise and Server. Unfortunately, KB4524244 was available for four days butMicrosoft has now stated it has been pulled for good."

"Microsoft is aware of Windows 10 KB4532693 critical bug"

jsrobson10: Yes, we can say it is Microsoft's fault. Even Microsoft is admitting to it.

And, some people may be mistaken when they say it is a POST error when it is actually occurring right after POST.

Some will Beep when everything is OK.

"If the computer passes the POST, the computer may give a single beep (some computers may beep twice) as it starts and continue to boot."

Others Beep only if there is a problem.

If your computer is beeping & not booting normally, you'll have to check for your specific BIOS & Computer as to what it means, since there is no standard.

For example, refering to the "Award BIOS beep codes", "because of the wide variety of different computer manufacturers with this BIOS, the beep codes may vary".

Since I am the IT Tech/Manager for a small town in Florida and I feel like I know what I am doing I would normally agree with you sir but it is obvious this is not normal. I read the information in these articles before posting this reply and it seems there must be a multitude of people who have no idea what they are talking about when speaking about their own computers or perhaps there is something more to this update than you may be aware but it is clear to me there is no such thing as a Categorically correct statement about these problems.

Perhaps you should try reading the articles as I did when things were not making sense.

I have learned in the 9 years I have been doing this that there is always the possibility for something to go wrong that we don't understand and is not explainable with what we know.
