In the last 12 hours, Windows XP Media Center lost my second core again. I blogged about this a while back where suddenly my dual-core system was only utilizing a single core - apparent in task manager, device manager and general performance. Even with 3GB of RAM, this sent things crawling in Virtual PC.
I'm guessing that some patch was dispatched today (Sunday) and the system stopped recognizing the second core. I wonder if anyone from MS and/or AMD is watching. I reran the driver that I linked to in my blog entry and all was restored. That's annoying.
I wonder how many dual core users are running 3 cans short of a 6 pack without noticing.
