We all have been easily able to do this prior to Windows 8 (in XP/VISTA/WIN7) with few changes in Registry and it was done.
With Windows 8 it's not that easy (I'm yet to figure it out how). Windows 8 too has few registry settings to be changed mentioned below, but along with this it also stores a unique Hash for every computer. Can any body help me to possibly create this hash for every computer or with some API to set default browser ('SetAppAsDefaultAll' does not work). Following are the registry entries.
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts.htm\UserChoice Progid : IE.AssocFile.HTM Hash : XXXXXXXXXXX
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts.html\UserChoice Progid : IE.AssocFile.HTM Hash : XXXXXXXXXXX
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts.xht\UserChoice Progid : IE.AssocFile.XHT Hash : XXXXXXXXXXX
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts.xhtml\UserChoice Progid : IE.AssocFile.XHT Hash : XXXXXXXXXXX
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\ftp\UserChoice Progid : IE.FTP Hash : XXXXXXXXXXX
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice Progid : IE.HTTP Hash : XXXXXXXXXXX
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\https\UserChoice Progid : IE.HTTPS Hash : XXXXXXXXXXX
Many Thanks in advance.
