How much hard disk space to install Win7

Approximately 30~35g's hard drive will completely install the Windows 7 system properly.

The smallest can choose 15G system partition, but such words need to do a series of optimization system to occupy hard disk space, turn off some caching function, avoid a system to hibernate and so on the system disk plug full cause panic or system crashes.

SSD is used as a system disk, but the capacity is small, in order to save the capacity of some column optimization operation, also apply to the mechanical hard disk.

If the capacity of physical memory has reached 4GB or greater memory capacity, then virtual memory can be lowered or closed.
