Windows 10 KB4512941 (Build 18362.329) is causing high CPU usage (Cortana eats 40% of your CPU)
Windows Latest ^ | Aug 31, 2019 | Mayank Parmar

Microsoft has just shipped Windows 10 KB4512941 to anyone who hits the ‘Check for updates’ button in Windows Update and click on the new ‘Download and install now’ option, which has been made available for optional updates or feature updates.

Windows 10 KB4512941 fixes the broken Windows Sandbox, black screen issue hitting Remote Desktop connections and several other bugs. However, some users have run into serious problems after installing the latest update that advances PCs to Build 18362.329.

According to various reports on forums (1, 2) and Feedback Hub, a number of devices may startup with a high CPU usage problem, degrading the overall performance of the systems. The culprit appears to be a botched version of Cortana that the firm has reportedly shipped in this release.

The Cortana (SearchUI.exe) process is generating CPU usage spikes for some users and the process has recorded a bump of around 30-40 percent in Task Manager, though the usage depends on the number of cores a processor has.

“After installing KB4512941 (OS Build 18362.329) the pop-out window with the search results stays blank, SearchUI.exe is constantly using CPU and ~200MB of memory,” a user documented the problem on Microsoft’s Feedback Hub.

“Cortana is consistently running above 35% CPU usage and 150 MB memory as reported by Task Manager, for at least one day now. Despite this fact, using the Search button next to the Start Menu pops up a dialog that will not display any items upon entering any search query, even after waiting for several minutes,” another user complained about the CPU usage on Feedback Hub.

It’s important to note that Microsoft actually tested KB4512941 with Windows Insiders in the Release Preview Ring for more than a week before shipping the update to the general public.

According to some posts on Feedback Hub, reports of high CPU usage were submitted multiple times by testers earlier this week, but the reports appear to have been ignored because they weren’t upvoted enough.

Some users have claimed that deleting a Registry key, which prevents the Start menu search from sending local search queries to Bing, resolves the CPU usage problem.

If you don’t want to play with Windows Registry, you should consider uninstalling the update. You can uninstall this cumulative update by following the steps outlined below: Microsoft hasn’t acknowledged the problems with the optional August update yet.

I have some home automation lights. The only way I can get Windows to work them is through Cortana. So, I undid the registry hack I used to disable her then said “Cortana turn on living room light.”

Then I heard my neighbor yell while my light stayed happily off. Not sure what she did but I put the hack back in with the words “never again.”

I thought so too, but my AltaVista search came up only with “Fenton.” I should have used my Netscape Vids library to find that great clip.

One of the first things I do is turn Cortana OFF. Will this help those who may have issues?

I have only watched it about 15 times.
Now without looking it up, what is the name of captain Pikes horse? ( That is my favorite ST trivia question.)

Linux works great. I have it on a single 64bit cpu box and it works faster than Windoze on a dual cpu machine

"Harcourt" at 1:10.

I am actually considering paying to upgrade to Win 10 Professsional. It has the means within it to put Cortana to bed and leave it there.

Presently I do get Cortana to temporarily go away, using task manager to continually kill it until it quits raising its head again. I will get relief for a while, but if my Windows session lasts long enough -like some hours - I will check task manager and Cortana will be live in the background again.

https://www.pcworld.com/article/3109900/you-can-remove-cortana-from-windows-10-but-its-tricky.html

The gpedit function is not available in regular Win 10. I did what was described as work around by downloading the Group Policy program and its folders, from MS, inspite of my system not being in a level higher than Win 10 Home. It did install a gpedit dll, but not the gpedit.msc; and gpedit as a command did not function in any way. It was as if I had downloaded nothing new into the Windows/System and Wondows/System32 folders.

I might pay for the Win 10 Pro upgrade and hope with it I can finally kill Cortana, or at least put to sleep for good.
