after clean boot it shows only 10gn of free space. I installed HS(1,5gb) and some very few, 1-10mb programs and have only 4,5 gn left. WTF? When i go to apps id doesnt show any ap that weights more than 30 mb, wth is taking this space. I installed 1,5gb game and have no space at all to install anything more. Windows and back up should take max 15gb and with hs it should be like 12gb left minimum.
