Windows 7 System Migration Guide-32-bit transition to 64-bit

windows--includes http://www.aliyun.com/zixun/aggregation/34065.html ">windowsxp,vista,windows 7 and the server version of the operating system- has transitioned from 32 bits to 64 bits. The hardware manufacturer has enough time to provide 32/64-bit drivers for their products. In fact, almost every scanner, printer, video camera, or other hardware device we buy now provides the drivers for both platforms. So if we buy a new set of equipment, we don't have to worry about compatibility. But what if we were to migrate the printers, scanners, or cameras that were previously purchased?

Although 32-bit programs generally work in 64-bit Windows, 32-bit device drivers are less fortunate. So far, there is no device in Windows that uses a 32-bit device driver and wraps it as an analog layer and then gets it in 64-bit Windows. This means that a lot of hardware, no matter how powerful, can be eliminated by existing users.

There is no reason for us to ignore this situation. Especially given the budget implications, we can take the initiative to avoid the consequences of trying to get the unsupported hardware back into the arms of 64-bit Windows. Scanners and printers are two very representative types of equipment, and because of the 64-bit appearance, both of these devices are excluded. We will analyze these devices and find ways to make them work properly.

Why upgrade to 64-bit?

First let's figure out why we're using 64-bit Windows. The desktop with 3Gb of memory is also installed by default 64-bit Windows. Because it makes the most efficient use of all memory space.

Perhaps, a separate 32-bit program requires very little memory, but for people running more programs, there is plenty of room for them to use. In addition, applications that perform a particular process, such as encryption, can run faster in a 64-bit system.

Not all computing devices use 64-bit. Netbooks and low-end computers with a maximum memory of 3G do not need to worry about the 32 to 64-bit transition problem. However, based on this, we believe that most senior desktops will use 64-bit, and the resulting device incompatibilities will increase. If you're not in a hurry, you can wait until all the incompatible hardware is eliminated and replace it with a new device. But for those who now have the hardware to use, waiting is not a good idea.

Does XP virtual mode help?

With the introduction of Windows 7 in place, Microsoft has provided dedicated support to its 32-bit 19803.html ">XP system, which uses virtual machines to run Windows XP to solve program compatibility issues." As a result, any program that needs to run in XP can be installed in a virtual machine environment, and it is running at a speed close to the local machine.

One disadvantage of this approach is that it requires the program to run in a fully-equipped windows and not interact with the host. Fortunately, Microsoft has launched an extension to this issue. An application installed on a virtual machine can run directly on your desktop and run as if it were on a real computer.

The main purpose of installing XP mode is to simulate applications rather than support devices. We can still run 32-bit device drivers in XP mode, but there is no direct device interface to use-we have to use other types of applications. In the case of scanners, we can use programs that get images from scanners, and for printers, you need a program that can perform print behavior.

List of USB devices that can be invoked by programs in XP virtual mode

Luckily, as long as we have an application that can talk to the device, the whole process is simple. Right-click the simulation application icon for the toolbar and we'll see a menu selection named Manage USB device. In this menu option, we can attack and use the USB device used by any problem program.

Note that we are not allowed to drag and drop files into a comprehensive application, but the main opportunity shows the associated network drive and we can browse the host.

Printer Migration printer is one of the most typical cases, it is possible to use your old printer directly in the new system, but it is very likely that you will try your best to keep the printer still.

If the printer cannot support commonly used PostScript or HP PCL, then we can install a generic 64-bit driver that matches the protocol. The generic driver does not yet have the ability to specify a printer, but it provides the underlying functionality to compensate for this regret.
