I wrote a program that I've been using on Windows ME and XP to apply a number of patches at once to the system.
The basic idea of how it works: There's an interactive mode and non-interactive mode. Select the patches (or provide the directory on the command line) and then it runs the patches then offers to reboot. More details are in the text file with the program.
