I would like to turn off Compatibility Mode for IE. I do not want to disable it.

For example, setting the following key to 9999.

REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION" /v "iexplore.exe" /t REG_DWORD /d 9999 /f
REG ADD "HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION" /v "iexplore.exe" /t REG_DWORD /d 9999 /f

This overrides the settings.

I have also found that via GPO: Admin Templates > Windows Components > Internet Explorer > Compatibility View > Turn off Compatibility View does the same thing.

I just want it to be OFF by default, and the user has control to change it.

It would also be nice to grey out the option: Display all websites in Compatibility View

I encourage you to check into using the Active Setup key.

In short, you can add a self-generated GUID to either:

HKLM\SOFTWARE\Wow6432Node\Microsoft\Active Setup\Installed Components, or HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components,

depending on your architecture.

Within this GUID key, add the following values:

(Default) REG_SZ <A name for your task>
Version REG_SZ <A version number for your task>
StubPath REG_SZ <The command you want each user to run>

Each user will run the command in the StubPath value once at logon. On subsequent logons, Windows will check the version number the logging-in user last ran against the Version key; if the Version key is higher the user will re-run the StubPath string.

I used procmon to figure this out.

I was hoping for a solution in HKLM... but unfortunately this is a user preference.

HKCU\Software\Microsoft\Internet Explorer\BrowserEmulation" /f /v AllSitesCompatibilityMode /t REG_DWORD /d "0"
HKCU\Software\Microsoft\Internet Explorer\BrowserEmulation" /f /v IntranetCompatibilityMode /t REG_DWORD /d "1"

So the way i would execute this is:

for /d %%X in (C:\Users\*) do (
reg.exe load HKLM\TempHive "%%X\NTUSER.DAT"
Reg Add "HKLM\TempHive\Software\Microsoft\Internet Explorer\BrowserEmulation" /f /v AllSitesCompatibilityMode /t REG_DWORD /d "0"
Reg Add "HKLM\TempHive\Software\Microsoft\Internet Explorer\BrowserEmulation" /f /v IntranetCompatibilityMode /t REG_DWORD /d "1"
reg.exe unload HKLM\TempHive )

I have to do a force log off to make sure the users NTUSER.DAT is not loaded. In my testing i had to run it at the logon screen.

Any other thoughts on deployment would be appreciated.

Just found this and noticed you didn't have an HKLM answer, so I'll provide what worked for me:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\BrowserEmulation]
