Remember that IE 8, 9, and 10 go end-of-life on Tuesday, January 12. If you have ConfigMgr, you can deploy it as a Software Update. You can also download it from https://windows.microsoft.com/en-us/internet-explorer/download-ie and deploy it as an application or package using this installation command:
ie11_package.exe /quiet /norestart /update-no
If you must continue using an old version of IE, you can put this registry key in place to stop the nag message:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_DISABLE_IE11_SECURITY_EOL_NOTIFICATION]
“iexplorer.exe”=dword:00000001
If you running 64-bit Windows, add this key as well:
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Mode\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_DISABLE_IE11_SECURITY_EOL_NOTIFICATION]
“iexplorer.exe”=dword:00000001
