Windows Search Error Win10 update (KB4512941)

I have a group policy in place to disable the Windows search from searching the web. Everything was working fine until today when update KB4512941 was installed. The search menu is totally nonfunctional, when I disabled the gpo and restarted the system, everything was back to normal. Is anyone else having issues with the KB4512941 update? I have since uninstalled it.

This is how the search menu looks now, no search results at all.

https://borncity.com/win/2019/08/30/windows-10-v1903-update-kb4512941-workaround-for-the-cortana-high-cpu-load-issue/

I had exactly the same problem as shown in your screenshot and a constant high cpu load of about 20% caused by Cortana. My System is Win 10 Home. What I did is what someone wrote here (in German):

Ich habe ja auch die Neigung in Win10 allerlei Firlefanz auszuschalten…

U.A. mit dem Tool OO Shutup https://www.oo-software.com/de/shutup10

Auf einer frischen Installation mit 1903.327 ( Ich weiß unkorrekte Schreibweise :) ) habe ich genau dann die hohe Last, wenn ich folgende Option aktiviere

Ausdehnung der Windows-10-Suche- via Bing deaktivieren [an/grün]

Lässt man diese eine Option auf default/AUS verhält sich das System normal.

I used the tool and turned off this switch "Extension on Windows 10 search with Bing" (green to red)

It's found near the bottom of the list. After a reboot Cortana worked like before and the cpu load was gone.

When pressing the Windows Key and F, nothing appears to happen. The update will not reinstall it's self as "*Your organization has turned off automatic updates" and I was the one who checked for updates. Not a permanent solution as I still will need to check for updates for security fixes.

My node is also hit by this. Why is it so difficult for MS to produce quality updates that would not introduce regression bugs? QA seems to have left the house quite some time ago...

Restoring the previous build solved the matter.

Now updates are almost monthly (for 1903, I notice 20 to 25 days gap). So, you can keep a watch on this and when new cum pack is released install that.

Keeping watch on releases does not help if MS's Quality Assurance processes are not working.

If once can trust various posts on tech blogs the issue been reported by preview testers but simply been neglected by MS.

From what I got as feedback KB4512941 seems to disable the GPOs. Beside to the other article linked above, I've created another blog post.

Windows 10 V1903: High CPU load from Cortana, Search broken, blame August 2019 Updates

I've mentioned some workarounds within my blog post. I will escalate this thread to Microsoft's moderators - hopefully they forward it to the developers. We have at least now 3 known issue:

  1. Windows Desktop search won't work, if Bing-Search is disabled.
  2. The Search GPOs are now non functional (as reported above)
  3. Cortana causes a high CPU load (100 % on one core)

You are mentioning in your blog post:

> This means that one of the August 2019 updates for Windows 10 Version 1903 causes these problems. Basically, it can only be the cumulative update KB4512508 that was released on August 13, 2019 (see Windows 10 Updates (August 13, 2019)). I haven’t another August 2019 update before August 30, 2019 in the Windows 10 V1903 history.

That did not happend on my node but only started to rear its ugly head with kb4512941. Related GPO on this node

and registry

I used Task Manager - Details - SearchUI.exe - End Task to stop the 21% - 36% CPU use . I would rather do this than revert to pre KB4512941 as it fixes lots of problems. Windows Search is still broken, but Everything search still works for me. I hope Microsoft fixes this problem on or before September Patch Tuesday.
