From a previously closed post, I was given a link which illustrated the mechanics of how to use the regsvr32 command in repairing the browswer, Internet Explorer. As I understand it, this command is used to register various core Internet Explorer libraries (urlmon.dll, shdocvw.dll, actxprxy.dll, oleaut32.dll, mshtml.dll, browseui.dll, and shell32.dll). I am not sure if I have that interpretation right. Assuming this technical interpretation is correct, what exactly does it mean when each of these library files of IE is being registered? Does that mean each one of these core files are being returned to their default condition? Additionally, why are these file referred to as "core" files? I assume this means these dll files are crucial to the basic functionality of IE, such as opening HTML pages, loading plug ins, etc.
In closing, any followup to my interpretations of the technical usefulness of the regsvr32 command will be appreciated.
