Installing Windows XP in Virtual PC

When you create a new virtual machine in Virtual PC (2007 and earlier), you choose the operating system you want to install on that virtual machine so that the virtual machine settings are optimized for that operating system. Now when you choose Windows XP from the list of operating systems, you get a default value of 128 MB for the memory, don't use that default value! If you do, Windows XP will take ages to install on your virtual machine, so, change the default value to be at least 256 MB. This will make a huge difference.
