What does “recommended security and compatibility settings” in IE 9 first-run wizard mean?

What does “recommended security and compatibility settings” in IE 9 first-run wizard mean?

  • Comments 2

 

By default, each user is prompted to choose 1 of below 2 options at the first run of IE 9.

·         “Use recommended security and compatibility settings”

·         “Don’t use recommended settings”

 

If you choose the first option, below 2 registry key values will be set to 1,

 

             HKCU\Software\Microsoft\Internet Explorer\BrowserEmulation\MSCompatibilityMode

If this key is set to 1, IE will download a site compatibility list from Microsoft website. The list contains compatibility information of some websites. IE renders the websites in a specific compatibility mode based on the list. See http://technet.microsoft.com/en-us/library/ff716425.aspx

 

             HKCU\Software\Microsoft\Internet Explorer\PhishingFilter\EnabledV9

If this key is set to 1, IE9 will enable SmartScreen filter version 9(compared to version 8 in IE 8). For more information regarding SmartScreen, refer http://windows.microsoft.com/en-US/windows7/SmartScreen-Filter-frequently-asked-questions-IE9

 

Note that both keys are set to HKCU, so that users can have isolated settings.

 

In case the second option is chosen, IE will set the above 2 key values to 0.

  • How the hell do you open this window to make the setting. Perhaps that piece of useful information might have been included. Typical.

  • They didn't open that window to make that setting, that window comes when you first install that version of IE, I recently installed a new version of IE and saw the same window
