Change default OS at boot up
By default, Windows Vista is the OS you will boot up in if you decide not to push anything at the boot-selection screen. However, this setting is changeable for those who would much rather have their earlier version of Windows become the default OS. You might be wondering why someone would want to do that? For instance, my brother is a very hardcore gamer but unfortunately, there is no driver support for my video card on Vista. Because he uses this computer more often than I do, the default OS on this particular PC is set to XP.
Now, let’s modify the default OS to start at bootup. First, go to Start Menu, right click on my computer, and choose properties.
