Hi SM, thanks a lot. I will provide it.
I'm curious with the IE11_main log on my first post. If you see the first part on 2017/10/13, it's the first time IE11 installed. After that finished, the IE11 version should be the base version 11.0.9600.16428 yes?
Then why in the second part on 2017/10/23, the log says "Previous version of Internet Explorer: 11.0.9600.18817"? When did version 11.0.9600.18817 installed?
I mean, maybe if I can rollback (on another uncorrupted machine) to base version before using "forfiles…" to remove IE11, I can prevent the corruption. As I mentioned before, on one machine with base version 11.0.9600.16428 the IE11 was successfully removed using "for files..".
