How much HDD space is needed for a 32-bit Windows 8 OS?

  1. 10GB

  2. 16GB

  3. 20GB

  4. 30GB

The correct answer is: 16GB

Windows 8 OS requires a minimum of 16GB of HDD space for a 32-bit system. Option A, 10GB, is not enough to accommodate the OS and any other necessary files or programs. Option C, 20GB, and D, 30GB, are both more than the minimum requirement and therefore, unnecessary and excessive. B is the right balance and the correct answer.
