I'm logged in to Win 10 r1903 as Admin, but can't open any ETL files in WPA with "access denied" error, despite run WPA as Admin. I can't also change ownership of any ETL file in itsProperties-Security-Advanced, and current owner is Unknown. When clicking Change Owner link, it switches to "You do not have permission" tab without showingChoose New Owner prompt. It happens only with ETL files, owner on other system files and folders I tried can be changed.
If WPA is aimed at viewing ETL files, why its unable to open them when run as Admin?
