Anyone else experiencing weirdness with their machine after installing Windows XP Service Pack 1? I’ve noticed after installing it, Internet Explorer will sometimes never return after you enter a URL. Once you close the window, the process (viewed via Task Manager) is using a LARGE amount of memory (around 30 MB), and cannot be terminated - even the “End Process” button won’t kill it. Attempting to shutdown will hang, since the system cannot kill the process, and I am forced to hold down the power switch forcing a reset.

Not exactly the most pleasant user experience.
