How much space should the Windows 7 C drive be divided into

A lot of users are helping us to divide the area when buying a computer. For some lazy users, this is of course good, but for some users who like to do it themselves, it is often not a good thing. The author belongs to the latter. The notebook that I use now is purchased through the Internet. It comes with the Ubuntu system, but the author does not like this Linux distribution, so all the partitions are deleted and formatted. Finally installed Windows 7 and Fedora on top. Many friends have doubts about the partition of the C drive. Under the environment of Win 7 Ultimate, how much space should we allocate to the C drive?

Generally our w7 system download Mirrors are all around 3GB. If you decompress this image, you will find that there are a lot of cab packages. This is Microsoft's own high-strength compression package. So it can be seen that when installing Windows 7, it is necessary to decompress the 3GB files, and the size of the decompression is generally around 8GB. This means that at least 8GB of memory is needed to install the win8 system. However, in the real world, Windows 7 requires more, because we need to use the other space of the C drive in the later use.
So the general minimum recommended installation environment is 16GB, but it is better to be above 30GB. We will not find that our C drive is always full during long-term use. When we use the system, it will inevitably generate a lot of system garbage, and these system garbage is often not completely removed by the system software. If you do not prepare a large space for the C disk, it may be very troublesome.
Don't stay in XP's thinking mode, now everyone has Win 8 download image, most of us use Win 7, this is a modern operating system, and the volume is not May be a small ghost win7.
