WindowsXPMode is based on Microsoft's VirtualPC virtualization technology, and combined with the hardware virtualization function of the processor, it can simulate the WindowsXPSP3 system environment in Windows7 professional edition, enterprise edition and flagship edition operating system. WindowsXPMode is actually a WindowsVirtualPC specially customized for Windows7, which can be regarded as a WindowsVirtualPC plus a legally authorized WindowsXP virtual machine. Of course, if your Win7 is a home version, you can't use this function. However, you can also use VirtualBox, a free virtual machine from different dimensions, and then install XP yourself, which has similar functions.
