Isn't sevenforums great? Actually, that's not what I meant, but it looks worth trying, if your system boots in the first place.
I only do repair installations if, as I wrote above, the system will not boot. I boot from the installation DVD, letting it detect my Win7 install, and choosing to do a repair. The link you provided looks snazzier, since it goes to the update site instead of working with files as of the date that the DVD was burned.
I gotta keep that link around.
