unix is a multiuser operating system but widows is a single user operating system.
That would depend on how you define multiuser:in the traditional timesharing sense and as Multics, Unix and VMS was designed to be multiuser, where it means many people may login to one computer at the same time via terminals connected to that computer, Windows is clearly NOT multiuser.As a system where many user accounts can exist on one computer and any of these people can login ONE AT A TIME and can access servers through a network that other users can access at the same time, Windows is multiuser.
windows does have the facility to give access to different users. That is the reason we can log on to different user accounts on windows. But windows does not give access to multiple users at the same time in a single processor system.
A multiuser database may exist on a single machine, such as a mainframe or other powerful computer, or it may be distributed and exist on multiple computers. Multiuser databases are accessible from multiple computers simultaneously.
Asphalt 8 will not be able to run on Windows 7. It can only run on Windows 8 and Windows Phone 8.

No
There is no Windows 8.
There isn't any Windows 7.8, but if you were referring to Windows Phone 7.8, it cannot be updated to Windows Phone 8 (note that I did not say Windows 8 because Windows 8 is for laptops, desktops and some tablets).
