Thin Disk on vSphere My First Glance

So today I got around to putting ESXi 4 on my spare box at home. I first deployed a new virtual server and decided to use the thin provisioning built into the new version. After getting everything all setup. I was suprised to still see this.

I was like DANG! that is some awesome thin provisioning. I was more thinking something had to be wrong. A 42 GB drive with Windows 2008 only using 2.28KB that is sweet! I thought for sure since I had not seen this screen on the information of the VM it had already refreshed. It was too good to be true though I clicked the Refresh Storage and it ended up like this. Which made alot more sense for a fresh and patched Windows install. So far this leads to my first question, why the manual refresh? Should this refresh automatically when the screen redraws?
