I don’t have the patience to go through a full install of Ubuntu but I also don’t think that running the Live CD does the operating system justice. If only there were an easy-to-use Windows installer that didn’t "require you to modify the partitions of your PC or to use a different bootloader." Enter Wubi.
Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the windows file system (c:wubidiskssystem.virtual.disk), this file is seen by Linux as a real hard disk.
