After installing Windows 7 Professional 32-bit with all Windows Updates up to today (Includes .NET Framework) it took up about 31 GB hard disk space.

However, I have 8GB RAM. After running Disk Cleanup, deleting other installation files, and disabling Hibernation and the Page File, I freed up another 12 GB.

You're looking at about 20GB after some tweaking.


They say approximately 15GB - 20GB will acquire. Official document is here.
