Win 10 update causing high CPU usage

Recent Win 10 update KB4512941 causes high CPU usage in Cortana. This lets Cortana eat as much as 40% of CPU time when/if you disable its ability to use Bing for local searches.

Three possible work-arounds until MS fixes their latest mess...

Re: Win 10 update causing high CPU usage

@dalem29   - Care to explain your comment?

The link I posted to BleepingComputer is safe and offers the details about the CPU usage issues with that MS update and offers some potential work-arounds.

Do you have any evidence to the contrary?

Re: Win 10 update causing high CPU usage

I confirm that link is safe, and the advice offered by Lawrence Abrams is good.

Yet more evidence of the wisdom of delaying these wretched updates for up to one month (my practice). Let others be beta testers ...

Re: Win 10 update causing high CPU usage

@joe53- Thanks for confirming that link is safe. I don't know why dalem29 posted that comment. He posted the exact same comment in my other thread on this forum which asks for advice on correct FF security settings for this forum, and I didn't even post any links In that other thread.

Just think about all the "fun" you're missing by holding off on these MS updates. Don't you want to be the first kid on the block with the latest bits of tech?

Re: Win 10 update causing high CPU usage

Ron: .

LOL - I surely don't miss the "fun" a-la-MSU

Seriously, I have been delaying installing MS updates for more than a decade with no adverse effects. I have certainly dodged several bullets due to update errors. The only exception I make is for the rare "out of band" critical security patches.

My rationale is that if MS feels it can delay releasing patches for up to one month, so can I.

Re: Win 10 update causing high CPU usage

@joe53  - I hear you loud and clear!  😉

And still waiting for @dalem29 to explain his issues with both of my recent threads...

Re: Win 10 update causing high CPU usage

Interesting...I was looking in Task Manager at the list of processes that are running on this Win 10 Pro, 64-bit lappy.

There's an odd icon shown next to Cortana on the list, and when moused over it says: "This UWP process is suspended to improve system performance".

Did MS sneak in a patch when I wasn't looking that suspends Cortana because of its high CPU usage caused by installation of KB4512941..??

FWIW, I NEVER use Cortana and I had disabled its ability to use Bing for local searches on the PC which is the condition that causes Cortana to eat up CPU time when KB4512941 is installed.

Re: Win 10 update causing high CPU usage

I notice the same icon/warning on my Win10 Pro x64 Task Manager, not only for Cortana but for another 6 processes. I have no idea what process is actually suspended, as my Cortana is fully functional to voice enquiries, although I rarely use it. And the Bing web search is working.

At one time I knew how to disable both (you can't uninstall Cortana) but the methods I have found on the internet lead nowhere for me at this time. MS has changed the GUI of Cortana settings. (I'm not going to try the RegEdit approach).

UWP (Universal Widow Platform) is a somewhat discredited app, according to the verge.

Re: Win 10 update causing high CPU usage

Sorry for the confusion, but the last time I came to the site a few days ago, someone other than you had left a comment on the two threads in question, giving some vague technical advice. The comment contained a link to a dot com website that appeared to be trying to sell something or trade merchandise. Knowing we should never click on any questionable links in the Dell forums, I issued a warning to other users in both cases, that it could be unsafe to go to that site...not sure if the links were clickable or not. This kind of issue has occasionally come up here before . I don't know who the unknown poster was , or who removed the comments. I have been coming here for years and don't have a reputation for causing trouble or making a scene. Once again, sorry of any misunderstanding.
