Forcing Internet Explorer Language Settings to a certain value

When working on multilingual platforms with browser-based applications, language settings are subject to change frequently..

So we had a problem about moss search and we had to set the language settings of our users to include both english & turkish (as seen in the screen below)

In our environment, the default value was only turkish

 it is very hard to apply this to all users; because there is NO policy setting for this configuration.

this is a nightmare, especially if you have >100 users

moreover, after you set the value the user can reset the IE settings 

so I explored a little bit and found out that this setting has a registry value.

"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\International"

create a file called langsetting.reg file containing this:

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\International]

"AcceptLanguage"="en-US,tr-TR;q=0.5"

and put it in a bat file which will run during win logon by 

regedit/s  langsetting.reg

and you are done :)
