Loss of fps on P3D after last update of Windows 10 due to Cortana

Postby robpol471 » Sun Sep 08, 2019 2:45 pm

After the last Windows 10 update KB4512941 I found a loss of about 15 fps on P3D.

I have verified that after starting Windows 10 Cortana always occupies the CPU for about 40%.

Only after having disabled Cortana using Start-Activity management- Cortana- End activity
employment drops to 1% (Desktop only) and fps on P3D return as before the Windows 10 update.

The deactivation of Cortana does not happen at the first End activity but it is necessary to do it several times, I have it
had to do 7 since Windows 10 not restarted Cortana.

Microsoft has released update KB4515384 for Windows 10 with the fix for the high CPU usage caused by SearchUI.exe.

It appears the latest patch may cause issues with some users:

Fortunately, for me, I never experienced the CPU spikes in the first place, and have no issues that I can see after installing both updates.
