And yet, people wonder why some of us would rather remain on Windows 7 and avoid Windows 10 like a plague.

And Windows 7 never had any update problems in all the years since it's been released?

Cortana issue, worm-able vulnerabilities occurring to article, privacy configuration reset on updates and 40% reduction in CPU performance which you need find a work around, since Win 7 does not contain Cortana or other spying issue that can hamper performance  I would say not.

Just to keep things in perspective, I have installed this optional update and everything is fine. Certainly none of my privacy settings have been reset.

No issues with this update, mind you, I don't use cortana either. CPU was at 2% idle.

Same here. No issues with update. CPU idle at 2% @ 4.9ghz. All cores @5.1GHZ

Apart from the Cortana issue (which doesn't seem to be affecting everyone anyway), I'm not aware of, or affected by, any of the other things you mention.

microsoft is looking into it:

When I listed the pass issues, I should have been clearer that the items I mention came from the Forbes article in the link from the OP, which complain about the quality control or lack of. It was related to Windows 10 upgrade 1903  quote from article “ Bluetooth connection broken, wormable vulnerabilities”

https://www.forbes.com/sites/gordonkelly/2019/09/01/microsoft-windows-10-update-problem-cpu-performance-warning-upgrade-windows-10/amp/

What does this have to do with the present issue with KB4512941?  It relates to the lack of quality control measure in releasing updates to the public. Tying this issue with Cortana with all the other pass issue with updates they mention in the article.

You may not have those issues I listed or you may have been more careful in how you upgraded your system but many others have based on the article. Which is why the OP was giving everyone here a heads up on this issue in case this latest release could potentially impact your system performance.

My opinion is based  on, when I am trying to make a decision as to whether or not I want to move to a newer OS and see things like this reported, then I would pause and ask myself do I want to endure this if my OS serves my need?  The answers are no. Because it does not offer me any compelling reason to switch other than if I need Direct12 support or going to a newer machine. At that point is when I will consider Window 10 and I'm sure there are others who fill the same who like me have not yet made the switch.

Yes if you read Microsoft own web update it started rolling out on the 30th Aug 4 days ago you may not have it yet I have blocked it, nothing installs automatically on my PC it has to notify me first.  

PS Microsoft now rolls out update using AZURE AI.

The biggest problem with articles from the likes of Forbes is that they're based on what users report online often without any attempt to look at the actual numbers involved. Even reports of bugs which seem to appear all over the Internet can be down to a small number of (usually very vociferous) individuals. There's often an illogical cause and effect link such as "I had an OS update last week and today my PC stopped working so it must be caused by that update". People then demand that Microsoft fix their problem having done no real investigation into its cause. Even if others have exactly the same problem, it's not necessarily the OS which has caused it. There have been plenty cases of people blaming the OS for problems which are later traced to something like a new, widely installed, graphics driver. Years of fault finding PCs, both at work and with friends and family, have shown me that most issues attributed to the OS subsequently turn out to have nothing to do with it and are hardware or non-OS software related. You only need to look through this forum to see how many apparent update problems have subsequently turned out to have had nothing to do with the update. The latest estimate for installed versions of Windows 10 is well over 800 million. Even if one million people have a problem after an update, that would be a tiny fraction of the total userbase and statistically insignificant.

I'm not denying that some people have problems with OS updates, but most (the very large majority) don't. When you're issuing updates for approaching a billion PCs, it's almost guaranteed that some of the (almost infinite) hardware/software combinations will have a problem. I think it's a testament to Microsoft's hard work that so many systems continue to work normally after the updates! As I said in an earlier post, I've yet to have a problem with Windows 10 after an update. On the other hand, I had several problems with Windows 7 updates over the years. Windows 10 has its quirks and there's certainly a learning curve involved when changing to it (just like all previous versions of Windows) but, for me, it's been far and away the best version of Windows so far.
