How much capacity does the system need to install 25?

My C disk is divided into 8G, and the installation of XP is 3G, and the remaining space is 5G, so this division is basically OK.

The C drive is generally installed with anti-virus software, and I install other programs in other disks. If you feel troublesome from installing the system, you can install a ghost, back up the C drive, if it is poisoned or damaged the system files, you can use ghost to restore the C drive.

It's good to be big, it's guaranteed, fifteen or ten. Generally, the guide disk is not less than ten.

6-7G for XP system, 13-15G for Vista system, it's as simple as that.

If it's an XP to 3G, it's enough....Go to the depth, and the next streamlined installation is 900m....

Generally, 10G of space is enough for the system.

Generally speaking, the C disk space does not need to be too large, too large will affect the speed of the machine, under normal circumstances, it is OK, and the paging of the virtual memory should be put into the D disk or E disk, so as not to affect its occupation of the C disk space, resulting in insufficient virtual memory of the machine, as for how to place the paging of the virtual memory, you can directly use the optimization master to deal with it, which is more convenient than artificially relying on Windows to operate the system. Moreover, software processing can effectively avoid the problem of machine restarting and the cumbersome problem of adjusting the size of the paging space caused by improper handling during human processing.

Of course, in fact, the system really uses space 3G is enough, but in order to upgrade the Windows patch in the future, it is better to use it larger. Generally, the configuration of the machine C is not greater than 10G, if you use Vista, it must be 15G, because its system eats too much space for the C disk!

Generally left and right It is better to have more points.

The installed capacity of 2 * 150,000 kilowatts is two 150,000 kilowatt power generation units, the installed capacity, the full name is "power plant installed capacity", also known as "power station capacity", refers to the total rated power of all steam turbines or hydroelectric generating units installed in thermal power plants or hydropower stations.

Definition of installed capacityThe energy index of hydropower stations may be greatly improved with the realization of cascade regulation and cross-basin compensation regulation, and the reasonable installed capacity of hydropower stations should be increased with the passage of time, and many hydropower stations in the world have adopted the scheme of phased construction, or expanded to expand the installed capacity after a number of years of construction, and China also has some hydropower stations with good regulation performance.

Due to the increasing load of the power system and the interconnection of the power system, the role and status of some hydropower stations with good regulation performance in the power system have changed, from the original construction to the power generation to the capacity efficiency, and the number of large thermal power units and nuclear power units in the system has been increasing.

1.Normally, after the installation of the Windows system is completed, it will occupy more than 10 GB of hard disk space, and will not exceed 20 Gbit. Therefore, the space division of the C disk must not be less than 20G space.

2.In addition, the capacity of the hard disk configured on the current computer.

are relatively large, and may be above 500g in general. For such a situation, it is recommended to divide the C disk space into larger ones, and it is recommended to be above 50G, such as 60G, 80G, 100G, etc.

3.If you have a small hard drive on your current computer, such as an SSD.

The capacity may be less than 500g, but in this case, it is recommended to divide it into 30g-50g.

4.In short, for Windows 7 and Windows 8 systems, the capacity of the C drive should be at least 25G space. Because after a period of use, the system will generate a lot of new data, which will be stored in the C drive.

If the C drive. If the space is too small, the C drive will run out of space, which will affect the overall support of the system.

To install win7, you need a hard disk of 30 35G.

The minimum system partition of 15G can be selected, so you need to do a series of optimizations to occupy hard disk space.
