I am working on an imaging process to be used for deploying new PCs. The imaging tool I use is KACE which installs Windows 7 x64 and then runs predefined commands to install programs and otherwise customize the machine. As part of the imaging process I install FF and Google Chrome. I want to set FF as the default browser for both the current user and all new users that login. The imaging process runs using the local administrator account, when the machine is delivered to an end user they will login with their Active Directory account, so that is why the default browser setting must be set for all future users as well. The mechanism for accomplishing this must be from the command line or via a script (doesn't matter what kind of script) as any manual interaction would defeat the purpose of this method of imaging systems. I have tried using "firefox.exe -silent -setDefaultBrowser" and have verified using process monitor that when I run that command things are being written to the registry, however it does not actually set the default browser to Firefox. I can verify that by going to Start > Run > www.google.com and observing that Google opens in a browser which is not Firefox. If I open Firefox and go to Tools > Options > Advanced > Set Default Browser and use the button there, then it does set Firefox as the default browser, but since that requires human interaction that is not a feasible solution. Can anyone offer a suggestion as to how I can accomplish this?
