Yes, In my personal Opinion Window 7 is the best ever Operating system but But i would focus Window 7 Professional rather than Ultimate Version of Window 7.
Windoes 7 has proved amazingly stable on a number of PCs I use. It's the best Microsoft operating system for sure.
Features and perks aside, W7 X64 is the most solid OS sold, generally speaking. I have the ability and experience to use any OS on the Market today, but Windows OS is the most reliable for a daily work related tasks. I generate more revenue a PC than a Mac.
Err, they are allowed on servers. It is called a domain. Every OS is meant to be good. Companies don't write operating systems with the intention of being crap. Some OS's just end up that way.
It's impossible to name a operating system as "the best operating system ever" simply because people use different operating systems for different purposes. For example, a person who is a very heavy video editor will probably prefer a Mac over a Windows or Linux system
Windows 7 is to my opinion the best operating system they have made until today. When Microsoft gives us the option to remove the Metro from Windows 8, this OS might be the better one. I do love how fast Windows 8 is.
nothing is better ever. there are always changes in version of window. window 7 is better than window xp in only efficiently working but window 8 i.e. recently coming window. window 7 have better looking than Xp but feature of Xp are surly Securtable than window 7 administrator power is strong in window Xp window 7 have chances to hack.
