OK, for grins I fired up Process Monitor, started Bing Sports (that never completes) and got 193,000+ events...

I searched for FAIL, didn't find anything, but I don't have access to that folder either. Hope I didn't break anything but I've taken ownership now. Nope, everything that DID work, still works... Interesting folder....

12/29/12 was the first install of the Bing ones, I assume that is kept as reference? USA Today doesn't seem to do that, and by the timestamps you can see I deleted and installed them today to test again.
I'm done... MS will figure this out someday. From the trace from Process Monitor it is too much to even digest and too many Registry hits...
Interesting though...
