Guys, I can't see Internet Explorer Maintenance add-in in Group Policy Management Console!
It was there and now it's gone. See, I have this policy configured and it works. So, what happened?
I am omitting here the necessity to import Internet Explorer .adm file to be able to manage it because it's another topic to describe.
This is example of what you can see: policy with IE maintenance set and no option to change settings:
Well, it's something that you probably didn't expected to be connected with - Internet Explorer version.
You've probably have had configured automatic updates on your server, haven't you?

2.If you can't uninstall newer versions of IE by any reason, you could use other server where you can see Internet Explorer Maintenance add-in, even if it's in different domain.
I've described how to do this here:
