Help! 10 Gb missing from Bootcamp

[macpcguy]

Hi,
I have a macbookpro 13.3' and I installed windows 7 enterprise using Bootcamp with 30 Gb space

I noticed that some space has been "lost". Not just 2-3 Gb but 10 Gb.

Bootcamp ( C: ) is showing 1.22Gb Free of 27.9 Gb
In the drive I checked each folder one by one and total is 16.6 Gb
Nothing in recycle bin

Where did the 10 Gb go? Does Bootcamp by itself takes 10 Gb space?

Windows will create ~10GB+ in hidden pagefile and hibernation files
