(x64) 

What version of window7 does it use?

Starter (Basic Edition) home_basic (family Base Edition)home_premium (home advanced Edition) professional

(Professional Edition) enterprise (Enterprise Edition)ultimate (Ultimate) which election?

1. starter (base version) does not take into account thefunction of less aero interface, and there are at most 3programs running at the same time limit

2.home_basic (Home Basic Edition) aero for small hard diskmachine configuration low user

3.home_premium (home advanced Edition) , most users choose toadapt to the computer requirements are not high, no need topursue all the functions of the user

4.professional (Professional Edition) is also the choice ofmost users, suitable for computer configuration good users

5.ultimate (Ultimate) , as its name implies, contains all thefunctions of win7 for the choice of the perfect pursuer

The starter (basic) home_basic (Home Basic Edition)home_premium (Home Premium Edition) is not only the grouppolicy professional (Professional Edition) enterprise(Enterprise Edition) ultimate (Ultimate) is not recommended todownload individual user group policy enterprise (EnterpriseEdition) is difficult to activate

Two, under 32 (x86) and 64 (x64) of the difference?

Windows XP, Windows Vista, Windows Server 2008, and Windows 7,both have 32 bit (x86) and 64 bit (x64) two versions. In theface of two versions of CD image download, often make somenetizens confused: which version is better to choose?Here, Iuse the simplest text as far as possible to make the mostdetailed answer: the five differences between the two". At thesame time, focuses on the Microsoft Windows64 bit (x64)operating system, compared with the 32 bit (x86) operatingsystem, what is the biggest advantage and disadvantage?1, different design intentions. The original design of 64 bitoperating system is: to meet the mechanical design and analysis,3D animation, video editing and creation, require a lot ofmemory and floating point performance and scientific computingand high performance computing applications in the field ofcustomer demand. In other words, they are platforms forhigh-tech people to use special software in the industry. Andthe 32 bit operating system is designed for ordinary users.2, different configurations are required. A 64 bit operatingsystem can only be installed on a 64 bit computer (CPU must be64 bits) . At the same time to install 64 commonly used software

to play the 64 best performance (x64) . Is a 32 bit operatingsystem installed in 32 (32 CPU) or 64 (64 CPU) on the computer.Of course, the 32 bit operating system is installed on the 64bit computer, and its hardware is like "big horse pull cart":64 bit efficiency will be greatly reduced.

3, the operation speed is different. 64 CPU GPRs

(General-Purpose Registers, general register) data width is 64bits, 64 bit instruction set can run 64 bit data instruction,that is to say the processor can extract 64 bits of data at atime (as long as two instructions, extracting 8 bytes of a data) ,more than 32 (four instructions a need to extract 4 bytes ofdata) doubled, theoretical performance will be improvedaccordingly 1 times.

4, addressing capabilities are different. The 64 bit processoralso reflects the advantage of systemmemory control. Since theaddress uses a special integer, a ALU (arithmetic logicprocessor) and a register can handle larger integers, that is,larger addresses. For example, Windows Vista x64 Editionsupports up to 128 GB of memory and up to 16 TB of virtual memory,while the 32 bit CPU and operating system can only support 4Gmemory maximum.

5, the popularity of software varies. At present, 64 commonlyused software than 32 commonly used software, much less than.The reason is very simple: using a 64 bit operating system useris relatively small.

Therefore, software developers must consider the input-outputratio, and put the limited funds into the software of more users.

That' s why the 64 software is relatively expensive, which costsless to sell.

In short, Microsoft Windows 64 operating system, must be "on"by the 64 host hardware support, "" on the 64 commonly usedsoftware to assist, to 64 advantage, "three-in-one" areindispensable (the truth is very simple: the operating systemis a nexus of the operating platform) . As for the 64 bit computer,you can install 32 bit operating system, and the 64 bitoperating system can install 32 bit software, which is thedesign of "downward compatibility", not the original meaningof the 64 design intention (as mentioned above) .

Finally, remind some netizens:

Although 1.64 computers can install 32 bit operating system,but 32 computers can not install 64 bit operating system. Thisis a crucial task to remember, to avoid blind download andinstall.

2. in the 64 bit computer operation of the 32 bit operatingsystem, can not take the hard disk installation way to install64 bit operating system. If installed, the preferred CD-ROMformat installation, you can also use more complicated DOSinstallation methods.

3. using virtual machines to install operating systems isactually installing software on the currently runningoperating system. Therefore, in the 32 bit operating systemcannot install virtual 64 bit operating system.

Three, under the MSDN version, OEM version, RTM version of whatis different

1 MSDN (Microsoft Developer Network) ) MSDN (MicrosoftDeveloper Network)

This is a Microsoft Corp version of a software developer for.MSDN covers the platform and the application can be extendedto all development, as Microsoft Corp Encyclopedia Encarta, ora variety of games, is not included in the MSDN, because theseproducts directly to the end user, there is no need for programdevelopment.

2 OEM (original equipment manufacturer)

Onlywith the machine shipped, not retail, socalled stochasticversion. Not only new installation, upgrade from the oldoperating system. If you buy a notebook computer or a computerversion of the software will be random brand. Unlike the retailversion of exquisite packaging, usually only one piece of CDand instructions (authorization) . This system is usually lessdriver, and the current version of OEM is rarely placed in theCD, you can install, or restore disk, or the hard disk mirror3 RTM (release.to.manufacturing)

In the formal retail store shelves, take a long time to press,packaging, distribution, so the code must have completed beforethe official release for a period of time, the completion ofthe program code named final.code, after the program code isdeveloped, to master a lot of pressure to the factory, this

version is called RTM version. The RTM code is the same as theofficial version. But the official version and have not the sameplace: for example, the official version of OEM cannot upgradeinstallation, upgrade to a new installation you will check theold version of the operating system CD, which is the RTM andthe official version of different places, but they are the mainprogram code is the same. Strictly speaking, this version stillbelongs to the retail version of FPP, which need to activate.Four, finally to provide you the official genuine Chinese win7full version download! (absolutely genuine Oh, copy the addressafter the thunder download, install all available Oem7activation)
