Internet explorer is already installed on this system

For specific compatibility reasons you occasionally need to uninstall Internet Explorer 11 and install 9 or 10.

You remove IE 11 from add remove programs. Download IE 10 or 9 and attempt to install it. You get the following message that claims " Internet Explorer 10 is already installed on this system"

From what I underrstood, apparently IE 11 is uninstalled but updates are not and hence the error.

I found the following script here that worked like a charm.


FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-*11.*.mum /c "cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /quiet /norestart"


Note: Ensure that you hide the Update to IE 11 in Automatic updates.
