You must have picked something up about the European Union that forced Microsoft to build a screen/popup in the Windows Operating System to let endusers choose between browsers…
As a System Engineer I want to decide which browser is used by our endusers, because we have a company standard!
So I started the search… howto disable that bloody annoying browser choice screen and here is the elegant solution:
Registry Key: HKEY_LOCAL_MACHINE\Software\BrowserChoice
Registry Name: Disable (REG_DWORD)
Registry Value: Enabled=1, Disabled=0
To deploy during a Windows build, use the following command, or by using a GPO:
REG ADD HKLM\Software\BrowserChoice /v Enable /t REG_DWORD /d 0 /f
