Hi
120 GB. Is size used by most engineers except computer engineers who use
1024 x 1024. 120 GB approx (1000 x1000) 7%.less is 113 GB
(1024 x 1024) according to windows explorer
Nothing practical you can do to increase the free space except wait until latest service pack and all updates installed installed then use disk cleanup and empty recycle bin
Regards
