I have many clients who are getting IE10 via Windows Update and cant view websites properly. I have set some of them to use compatibility mode, but this still doesn't work since it is still using IE10. I need to figure out how to set IE10 to always open in IE9 browsing mode. I know they can press f12 and change the browser mode there, but this seems to last only for that session. Any help is greatly appreciated.
You can use the FEATURE_BROWSER_EMULATION feature of Internet explorer.
Start regedit.exe, go to
create a DWORD iexplore.exe and set the value to 9999 (0x270F).
Some sites look bad in IE9 (GMail being one). I found that pressing F12 to get the developer console then switching from compatibility mode to "Internet Explorer 9" mode fixed the problem. However, when I restart IE this setting is lost.
How do I make it persistent?
I am on Windows 7.
Under the tools menu (not the gear icon in the upper right corner) you can use the compatibility settings option to add sites to be always viewed in compatibility view or set all sites to be viewed that way. If you cannot find the tools menu, click 'Alt' to show the command bar once or right click the title bar and choosing 'Command Bar' from the menu to show the command bar all the time.
