Set Internet Explorer 10 to always open in IE9 browsing mode in windows 7

Question

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.

Solution

You can use the FEATURE_BROWSER_EMULATION feature of Internet explorer.

Start regedit.exe, go to

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

or

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

create a DWORD iexplore.exe and set the value to 9999 (0x270F).

Real answer: fix the web sites they're visiting. :)

Lol True Story. I wish I could, but most of them are medical related sites and they dont support IE10 yet due to "potential security holes"

Secondary answer: Prevent IE10 from being download via Windows update.

I use Internet Explorer.....to download Chrome. do these sites function properly on other browsers? can your users use these other browsers? like say Safari? I imagine a lot of the users being in the medical field are probably using iPads or Macbooks(or whatever they are called these days)
