I had problems all day and just found IE 10 installed. I didn't want it and I didn't make any selection to install it. Is this being pushed out randomly to see if anyone notices? I sure did. That's just plain dumb on Microsofts part.
Automatic Updates will only offer Internet Explorer 10 to users with local administrator accounts. Automatic Updates will automatically download and install Internet Explorer 10 when it is available for Automatic Updates delivery. There will be no notification or prompt to indicate the installation process. Users who are not local administrators will not be prompted to install the update and will thus continue their currently installed version of Internet Explorer.
Internet Explorer 10 will replace Internet Explorer 8 or Internet Explorer 9 on a user's computer. However, users may roll back to Internet Explorer 8 or Internet Explorer 9 by uninstalling Internet Explorer 10. Windows 7 and Windows Server 2008 can uninstall through the Windows Control Panel Programs and Features utility under the View installed updates option.
Note:
If a user has installed Internet Explorer 10 and subsequently removes it, Automatic Updates will not re-offer Internet Explorer 10 to that computer. Internet Explorer 10 will no longer be presented by Automatic Updates.
