Microsoft support
number looks like the issue could be caused by an update to Cortana (listed as SearchUI.exe in Task Manager), which is causing
processor spikes of around 30% – 40%, as well as constantly using system
memory, even when not in use.
What’s particularly
annoying about this problem is that the Windows 10 KB4512941 update was tested by Windows Insiders in the Release
Preview Ring before Microsoft support phone number was made available to
everyone, and according to some posts on Microsoft helpline number Feedback Hub
(an app that allows Windows Insider users to report issues in early versions of
Windows), users had reported these CPU issues.
However, Microsoft
support number seems those reports were ignored, and the update was released
anyway.
How to fix Cortana's high CPU usage
Microsoft support phone number looks like some users have found a fix for the
problem, though it does involve editing the Registry. As ever, if you do edit
the Registry, make sure you back up first, and be careful.
Open up the Registry
by pressing Windows + R on your keyboard and type in 'regedit'.
Open up
'HKEY_CURRENT_USER' then browse to
\Software\Microsoft\Windows\CurrentVersion\Search.
There, you’ll find a
registry entry called 'BingSearchEnabled'.
Select it, and set the 'Reg Value' to 0.
This will stop local
search queries you perform on your PC being sent to Bing, Microsoft helpline
number online search engine, which looks like the main cause of the high CPU
usage issue.
You can also fix the
issue by uninstalling the update by opening up Settings, clicking 'Update &
Security', then click 'View update history'. Click 'Uninstall updates' then select the KB4512941 update and click 'Uninstall'.
It’s a rather
embarrassing problem for Microsoft customer support, especially as it should
have been caught before the update was rolled out to the public, so hopefully
the Microsoft customer support releases an official fix soon.
