NT does have backward compatibility. You can use every NT program on every NT based platform. DOS platforms however are completely different.
I think you've got that backward. There is no version of Windows known as "Windows 2007." Windows Vista was released on January 30, 2007.
With most setups Windows 8 will run any Assassin's Creed game. If you have trouble like I did you can use the capability settings torun back to an older version.
Yes.
It means that the new version of something will still work with things that the previous version worked with. For example the PlayStation 2 is somewhat backwards compatible with the PlayStation 1 because you can play Playstaton 1 games on the PlayStation 2. It is not completely compatible however because not all of the PlayStation 1 accessories work with the PlayStation 2.
i think it the full version for windows 8 or its a trial version for windows 8, if not full version.
No version of Windows currently uses a microkernel
Executing DOS commands in a Windows environment, you mean? It actually depends on the version of Windows you're running. But with the exception of Windows ME, almost everyone of them has the capability to execute DOS commands. Try using the "run" command from the START box and type "cmd". That ought to get you started.
Windows 9!
No, that is not true. Windows 7 has the capability of writing to a CD.
Windows 3.0 is not a version of Windows available for the Windows Vista GUI. Any version of Windows before Windows 2000 are also not available.
Windows Vista.
My Windows 7 laptop has Version 5.5.0.124 - if that's any use !
