Vista SP1 (one week later)

There it is again. The glass ceiling:



A couple of days after the SP1 install, My OS stopped responding two days in a row and I was back at 3.4. I scrolled back the chart to see where that behavior started. I have had this 2-3 week cycle of "up to 6.5, back down to 3" stability index since February 13. I looked at the software installs for that day and there were a whole whack of things:

• Many updates from Microsoft (half a dozen or more)
  
• Adobe Reader 8.1.2 install
• Many drivers were updated too (touchpad, keyboard, USB mouse, ATA adaptor)

The Adobe Reader looks like a winner to me. Using autoruns, I figured-out that it automatically starts a "speed launcher" utility when Windows starts. I disabled that. Let's see what happens in a couple of weeks.
