(Edit : I found out why it installed any way. In windows 8 you have to make sure that you deselect unwanted updates in both the 'Control Panel'->'Windows Update' (classic desktop) & 'Settings' ->'Change PC settings'->'Update and Recovery' (Tile UI) before allowing the updates to apply)
ok, I thought, I'll just apply the registry disable key
HKEY_LOCAL_MACHINE\Software\BrowserChoice\Enable=0
('Enable' is a DWORD )
after much searching and googleling around I finally found the solution. you just have to remove the shortcut to it in
C:\ProgramData\Microsoft\Windows\Start Menu\Programs
