Windows performance without IE

I am writing this mini-post, still being impressed by the recent discovery:
Not all sections of microsoft.com can be accessed without Internet Explorer!

I tried to turn on updates for Microsoft products in Windows Update.
Click “Get updates for other Microsoft products. Additional information "- no result. But after this link I had to accept the terms of use for Microsoft Update!

I was confused until my colleague suggested - what if the link is trying to open in IE?

Most of all, it was the “silent” ignoring of the link that alerted without any errors, warnings, etc.
From this I conclude - Windows, sometimes, is demanding for the presence of IE, and leave it "just in case."

PS if it was my cant, then I will be grateful to the one who will explain the CHyaDT.

update:
At the beginning of the history of IE, along with some other components was removed, because they did not use.

update 2:
The operating system is Windows 7 Ultimate (Russian) x64.
