Download update Windows xp service pack 2 Movie Maker

Windows 7 comes with "Windows Live Movie Maker", check your program listing for that description.
There is no Service Pack 2 for Windows 7 that I know of at this time.
Do not download XP service pack 2.

Windows live movie maker appears to not have "Capture from device"option. Which I need. But in any case , when Windows live essentials(inc windows live movie maker)......wlsetup-web, is installed,a window appears telling me movie maker " cant start".
I purchased my computer with Window 7 already installed. I prefer windows XP.
I tried install service pack 3 but appears windows 7 dont run with that.

You cannot blend service packs from one OS to another.
Movie Maker should not run on Boot.
Type in run box - msconfig.msc and remove movie maker from boot process.

Here is the response for "run"
"Windows cannot find msconfig.msc make sure you typed the name correctly and try again"
But anyway, I already uninstalled Movie maker from control panel uninstall programme.
