title: AWS EC2 High CPU alarms going off
body: <p>I have a micro EC2 instance running windows 2008 R2.  I've been getting a lot of high CPU alarms going off lately, and when I log into the AWS management console I see that my CPU is practically pegged at 100%.  However, if I log into the instance and pull up task manager, my CPU looks like it's practically idling.  I've left task manager open for a while and took this  screenshot showing the differences between was AWS is reporting and what my instance looks like it's doing.  Suggestions? </p>

  <p>PS: the update speed on task manager is set to "Low"</p>
