How does Windows 7 solve software compatibility problems?

Q: How does Windows 7 solve software compatibility problems?
A: The reason why Microsoft Vista has no XP success is precisely because of its compatibility. So for Windows 7, Microsoft has made great efforts in program compatibility. First of all, Windows 7 guarantees compatibility for programs that can run normally on Vista. But for those programs that can run on XP but can't run on Vista, Windows 7 is not compatible. For incompatible programs, we can try to run in compatibility mode by:
right-clicking on the program that needs to run in compatibility mode, selecting the attribute item (the last one in the menu), then switching to compatibility The sex label, as shown below, can be selected, XP or Vista compatibility mode to run. However, this is not a cure-all way, many programs still can not run perfectly on Windows 7.
Microsoft has let those programs that can only run on XP, can also run normally on Windows 7, deliberately released the XP Mode program, using virtual machine technology, virtualize the program to Windows 7, but unfortunately XP The mode has certain requirements on the hardware of the machine. Many old machines do not support it. I hope that more machines can be supported when it is officially released. And XP mode only has the advanced version of Windows7, and the home version does not have this feature.
