How to speed up Internet Explorer 6.0 Favorites

For some reason, the Favorites menu in IE 6 seems to slow down dramatically sometimes.

I've noticed this happens, when you install Tweak UI 1.33, for example, and when you use the preview tip to speed up the Start menu.

But here's a fix for the problem that does work, though it's unclear why, just open a command line window (Start button->Run->CMD) and type SFC, then hit ENTER.

This command line runs the System File Checker, which performs a number of services, all of which are completely unrelated to IE 6. But hey that works even though it is not related.
