Compatibility of Windows XP Professional x64 Edition

As can be seen from the above content, for 64-bit Windows, the average computer user No need to think about it now. For example, if you usually just chat online, watch movies, and use Office to write files, then the existing 32-bit Windows can meet your needs very well. For now, one of the biggest disadvantages of 64-bit Windows is compatibility, and the most prominent one in terms of compatibility is the drivers for various hardware devices. If you are already an old user of Windows, then you must still have an impression of this. When installing certain hardware under Windows XP, the operating system does not come with a driver for the hardware for Windows XP, or the hardware development does not The corresponding version of the driver is provided. We can also try to use the driver of the device under Windows 2000. If you are lucky, it can also be used under Windows XP. However, the situation is completely different under 64-bit Windows. The hardware drivers for 64-bit and 32-bit Windows XP cannot be mixed at all. That is to say, if the developer of the hardware device you are using has not developed a driver for 64-bit Windows XP, driver, then either the device cannot be used under 64-bit Windows XP, or it can be barely used using the universal driver that comes with the operating system, but performance and functionality will be affected.

As for other software programs, there are generally no major problems. In 64-bit Windows XP, only 16-bit applications are completely unusable, while 32-bit applications can continue to be used. However, you should also pay attention when installing these applications. Although some applications have nothing to do with the hardware, in order to realize certain special functions of the software, drivers will be installed into the system at the same time when installing the software. This This program cannot be used under 64-bit Windows until a 64-bit version is released.

For example, the famous screenshot software SnagIt will install a virtual printer into the system when installed by default, which can output documents into graphic formats. Because a virtual device is installed, the program does not yet provide a 64-bit version. Therefore, when installing with the default options under 64-bit Windows XP, an error will occur unless we customize the installation options and do not install this virtual printer.

Similarly, almost all current virtual optical drive software and anti-virus software cannot be used under 64-bit Windows XP.

I would be honored if you could help!
