How much system disk does it take to install the Win7 flagship 64-bit system?

1, Microsoft released the official data is 20GB of hard disk space (note that the official release does not include patches, such as space occupancy);

2, analysis of the system disk usage:

A 64-bit Win7 operating system, to be installed on the systems disk;

b) Operating system patches, the more patches will be more;

C Install Office, QQ and other software needs of the system disk associated programs also occupy the system disk space;

d The Internet, software operation, patch upgrades, etc. also need to occupy the system disk space;

E The program that must be installed on the system disk;

3, through the above analysis, 20GB of space is not enough, 64-bit Win7 system disk is the most appropriate, small series of practical use and network name feedback, 64-bit Win7 system disk at least 50G, recommended 60G above, if you know that there is a need to install the program in the system disk in accordance with the actual size of the program can increase , the hard disk is big enough to consider 100G oh, so that can better run up.
