SearchUI.exe missing from Windows 10 64-bit

[maitaioneone]

Hi,

I have an Acer Aspire R, running Win 10 fully updated, Avast Free 21.6.2474 (build 21.6.6446.683). 

My SearchUI.exe file is missing. 

I am unable to do a Windows Search Bar search and pull up files.  Is there a setting in Avast preventing this? 

Thanks

As far as I'm aware there is no Avast interaction on this (or you would have had an alert or message).

Where are you searching from ?
A screenshot and any error message you are getting may help.

A windows update may have been involved, you say your copy of win10 is fully updated, if so apparently searchUI.exe has been changed/renamed to SearchApp.exe, but this happened some time ago.  I did a search on searchUI.exe and got this attached image at the top of the listings.

EDIT: if you are searching from the Magnifying Glass icon on the system tray, that works on my system.
