Hi @NicxNoob
Are you using one of these methods to disable Internet Explorer on Windows? If so, I think it can only disable IE app.
I made a test that disable Internet Explorer in Windows Features, then use WebBrowser Control which is based on MSHTML engine. WebBrowser Control can still work after disabling Internet Explorer. So I think it can only disable IE app.
Besides, as far as I know we can't disable/remove MSHTML in Windows as it's a part of the operating system.
