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).
