Windows7 may drain battery faster than Max OSX on MacBook Air 11"

I was intrigued at how fast the battery drained while running bootcamp on my MacBook Air 11" (2011 model).  There are various blogs discussing how Windows is not SSD friendly, particularly Vista, however I felt this would have been resolved with the latest version of Windows and/or latest service packs.

After various trials and errors, I achieved reasonable battery life by turning off Windows Search which has indexing running in the background.  Simply turn off the service called "Windows Search" and change it's startup to either "Manual" or "Disabled".
