As of today, Microsoft is only providing support to the the latest version of Internet Explorer, IE11. It will continue to receive security updates while older versions do not.
Microsoft has had this information posted on their site under Windows for Business. They encourage individuals to upgrade their browser to IE11 or upgrade their computer to Windows 10 and use Microsoft Edge. For enterprises, they encourage them to update and use Internet Explorer Enterprise Mode to improve compatibility mode.
Along with the end of security updates, non-security updates, support options, and technical content, Microsoft will begin prompting (nagging) those on older version of Internet Explorer to update. KB3123303 explains the “new ‘end of life’ upgrade notification for Internet Explorer” including how to opt out. To disable the prompt, you can create a Registry key.
32-bit computers create the key and entry under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_DISABLE_IE11_SECURITY_EOL_NOTIFICATION
Name: iexplore.exe
Type: DWORD
Value: 1
64-bit computers create the keys and entries under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_DISABLE_IE11_SECURITY_EOL_NOTIFICATION
Name: iexplore.exe
Type: DWORD
Value: 1
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_DISABLE_IE11_SECURITY_EOL_NOTIFICATION
Name: iexplore.exe
Type: DWORD
Value: 1
Central Management
Pushing this Registry key through Group Policy Preferences might make it a bit more manageable. You can also use the architecture variables with item-level targeting to ensure the 64-bit/32-bit keys reach the right locations.
