Microsoft has ended its support for older IE8/9/10 browsers, leaving only the latest version of IE11. Maybe you don't like IE, you may not use it at all, or even want to uninstall it, but even so, you still need to upgrade to IE11. Microsoft Development Engineer Pat Altimore a special article explaining why. He said that although IE is a browser, but many modules are shared with the system, including the JAVASCRIPT/THML rendering Engine (MSHTML.dll), Browser Control (Ieframe.dll), the Windows Internet Protocol Handler (WinInet.dll), While the browser's core main program (IExplore.exe) needs to use them to perform various operations, upgrading the browser is essentially upgrading these modules.
He stressed that in order to keep these IE related system components are up-to-date, you need to upgrade to IE11, and even to completely remove IE, you must first upgrade to IE11 again.
In addition, "Enable and disable Windows features" in the control Panel can only hide IE, not completely deleted. In fact, IE is not completely deleted, because it is closely related to a series of Windows systems (which is one of the reasons that browser makers accuse Microsoft IE of monopolizing it). When you make security and update patches to the entire system, IE is actually also accepting upgrades, even if you don't use it.
