I found an article on "Trustedinstaller" as follows:
https://helpdeskgeek.com/windows-7-how-to-delete-files-protected-by-trustedinstaller
Working in Windows 10 - Found 4 files listed in Windows/system32
as follows -- Microsoftedgebchostel.exe, Microsoftedgecp.exe,
Microsoftedgedevtools.exe, Microsoftedgesh.exe..
I was able using this tool to alter the permissions to let me
alter the name of the above 4 items. I took off 1 letter before
the ".exe" for each file.
I then ran Ccleaner and it showed that Microsoftedge was still
functioning. According to what I did in Windows/system32 it should
be totally disabled....
