Many users are not able to distinguish between 32-bit and 64-bit systems. They don't know how to choose these two versions of Windows 7 system. Today, the system home Xiaobian came to talk with everyone about the difference between 32-bit and 64-bit. For many users, how to choose the wind7 version when installing the computer is a very headache. How to choose according to the specific situation? One of the well-known things is the 64-bit system operation execution rate and hardware utilization. The rate is much better than the 32-bit system, and the 64-bit system is better for 32-bit system games and various software compatibility, so more and more software vendors are leaving the 64-bit version, and more and more The more users are willing to choose a 64-bit system to install. But you know, not all computers are free to choose whether to install a 64-bit system or a 32-bit system. In general, a 64-bit system requires more hardware configuration for the computer. However, in today's scientifically advanced world, the hardware configuration of many computers is constantly improving, so many people are willing to choose a higher level to install when installing the system, so that users can enjoy higher speed and Stable enjoyment makes it easier for everyday work and study. Today, Xiao Bian came to talk with everyone about the difference between 32 and 64, let us figure out the difference between the two, bid farewell to the technical rookie. The difference between 32-bit and 64-bit #1, which computers support 64-bit Windows 7? Generally speaking, except for those low-end CPUs that do not support AMD or Intel extensions, most of the computers produced in the past 3 years are Ability to run 64-bit Windows 7. For example, Intel Atom low-power CPUs and earlier Intel Intel Core CPUs (such as Core Duo instead of Core 2 Duo) do not support 64-bit Windows 7. If you are not sure which CPU is configured on your computer and if the CPU supports 64-bit, then you can use the free Intel processor identification tool to identify. #2, How to identify whether external devices are compatible with 64-bit Windows 7? Most Vista-compatible peripherals can work with 64-bit Windows 7. However, the introduction of 64-bit is indeed a blow to traditional hardware support. . The best solution is to use a web search to view 64-bit device drivers to support 64-bit peripherals. #3, Can users use 32-bit device drivers in a 64-bit version of Windows 7? No, the device driver code can only run in the same address space as the Windows kernel. Therefore, the device driver must match the architecture of the kernel itself. Some manufacturers bundle 32-bit and 64-bit drivers in a separate installation package, which leads some users to think that 32-bit drivers can run on 64-bit Windows operating systems, but it is not. The difference between 32-bit and 64-bit However, although the 32-bit driver cannot support 64-bit Windows 7, 64-bit Windows 7 users can install 32-bit drivers in "Windows XP Mode" and A 32-bit USB printer and other peripherals are used in the Windows XP virtual machine. #4,“Windows XP Mode" Can I run on 64-bit Windows 7? Yes, 64-bit Windows 7 can fully support Windows XP mode, in fact, using virtual machine monitor (VMM), similar Support for Windows virtual machine products "Windows XP Mode" is the only way to use 32-bit device drivers under 64-bit Windows operating systems. However, users should be aware that peripheral devices must be connected to the computer via a USB interface. Traditional hardware using a proprietary expansion card or dongle may not work with “Windows XP Mode. #5, What is the specific mode of Windows XP? How to get the "XP mode"? The answer is very simple, "Windows XP mode" is actually a virtual system that contains "Windows XP SP3" in Windows 7 system environment. machine. Windows 7 Professional, Ultimate and Enterprise users can be downloaded for free through the Microsoft Download Center. The difference between 32-bit and 64-bit, more accurately, Windows XP mode is a 64-bit application that can create a stand-alone, local 64-bit process emulating a 32-bit PC environment (actually, a series of 64-bit services and devices) driver). #6, Can users run 32-bit Windows applications in a 64-bit Windows 7 environment? Yes, almost all 32-bit Windows applications can run seamlessly on 64-bit Windows. #7, When installing a 32-bit application in 64-bit Windows 7, why can't I see its registry key? 64-bit Vista and Windows 7 have a 64-bit to 32-bit conversion layer, 64-bit Windows can Register 32-bit applications independently and import them into the appropriate registry hive. #8, Will you get the performance advantage of using 64-bit Windows 7? The difference between 32-bit and 64-bit depends on the specific situation. If you are using a large file and application, you need to consume a lot of memory. , then using 64-bit Windows 7 will have obvious advantages. This is because 64-bit Windows 7 can support physical RAM far beyond 32-bit Windows 7, and also supports application extension mode. #9, Why does 64-bit Windows use more RAM than 32-bit Windows? Any 64-bit operating system consumes far more memory than 32-bit Windows, depending on the 64-bit code. It's not surprising that 64-bit operating systems use larger internal structures and will take up more space (whether memory or hard drives). #10, Is 64-bit Windows 7 a security advantage over 32-bit Windows 7? Yes, many core security features require 64-bit support, such as data execution protection and patch protection, in addition to 64-bit Vista or Windows 7 will also provide users with digital signature protection for device drivers. #11, Can users perform 32-bit Windows to 64-bit Windows upgrades? No, at present, the Microsoft Windows upgrade process does not support migration between processor architectures. If users want to upgrade from 32-bit Windows to 64-bit Windows, then they must perform a 64-bit Windows "Net Install". In addition, I would like to remind everyone that although some versions of 64-bit Windows 7 can provide "Windows XP mode" to solve backward compatibility issues, but "XP mode" is not a panacea.
