What is your system folder's size? [GA 3+]

Hey guys,

I was just cleaning up my SSD, realizing, that my system's folder (Windows 7) is exactly 30 GB large. Which made me wonder what other people's size is. cough

Of course there's old (driver) backups and other trash to be found, too. I think page and hib files aren't included. However, just check it right now without any modifying and vote. I know there's differenes between occupied and used space. Just vote for the occupied size (of your main computer's system). I'm curious to see the results. If you want, you can post your OS in the comments, too.

Also checked my Windows 8 and XP systems:
W8: 23 GB
XP: 6 GB

And here a fitting giveaway for your effort.
