So, you got windows XP Home. It didn't come with windows movie maker, did it?
I wrote a simple batch file that you can use to update your version to 2.1, hopefully the good folks at Microsoft won't try to sue me for helping you by providing some of their files here.
What you need to do next. Download this zip file.
Now to create a system checkpoint with system restore. Where is it? See the picture below
Next step, extract the files from the zip file to a folder, like C:\TEMP
When that's done, locate the file called install.cmd in the folder you just unzipped the files into and double click on it.
THAT'S IT! You're done.
