Now for the review.
The first point I want to address is the same as the most important. The performance increase.
The performance of Windows 7 is the forward from its predecessor by far. To take one small example. On Windows Vista, my PC has a performance index of 5.6, highest rating a 5.9. In Windows 7, all components scoring 7.1 and also affects heavily on my applications. The best example of Far Cry 2. If I 2 turn on the Direct X 10 mode on Windows Vista in Far Cry, based on the game. When I go to Windows 7 Far Cry 2 games can I make all the settings to maximum and Direct X 10 on and you can feel in the game not a single stuttering. To my hardware is to say that most of the components of my PC are far older than the mentioned game. And otherwise, the system makes a very solid and quick impression. From the time of turning on the PC until the date on which it is up to 100% pass a maximum of 2 minutes. The performance increase is simultaneously connected to substantially lower hardware requirements than Vista. One can say that on any system on which Vista is going well, Windows 7 is still running faster. I think even older computers the Mostly still should work with Windows XP have no problems Windows 7 fully execute.
On the stability there nor any complaints. I use the system for a week now the whole day and had been neither crashed nor any annoying error messages that are well known to me from earlier days. Not least, the blue screens that came every now and then when I booted Vista.
The look has changed again when compared to Vista. While there continue to gadgets such as watches, calendars and slideshows, but without sidebar. This was abolished and the applications can be exposed on the desktop at any desired position or can be docked to the side of the screen. The biggest visual change brings the new taskbar itself, which is in my opinion turned out beautifully. Not doing so will no longer appear here as long text bar, but only represented by their program icons. They are also grouped immediately. This means in plain text the following: you have eg multiple Word documents open, you can see in the taskbar only the typical wordpress blue W. Assuming the mouse on this W opens another window which displays all open documents. The possibilities for desktop composition were also a bit improved. For example, it is now possible not only to select a background image, but equally full of it then change a whole pot in freely selectable time intervals.
Who's afraid that his old programs driver, etc do not run on Windows 7, which should now be careful. Because this Windows 7 has a simple solution. In the Control Panel, there is a tool which is able to avoid this problem. Again, I have an example. My board (ASUS Maximus Formula II) had a CD accompanied with drivers specifically for Windows Vista. If you try to start them under Windows 7 is only an error message that one says that this was not possible. Also manually can not install the drivers. But to use the above-mentioned tool can be any drivers install without any problems and they work after properly. All want the tool to know is, what program you want to install (select exe) and under which system it was still running (eg Vista) and the tool does the rest.
There are a lot more could I tell of the here but I think that's enough for now. So I can only advise everyone to try out Windows 7 or to upgrade. In my opinion it is the best operating system that Microsoft has ever developed, real high praise for it.
So again: BUY !!!
My system:
Intel Core 2 Quad Q6600 (4 x 2.4 GHz)
8GB DDR2 (1066 MHz)
ATI Radeon HD 3870 X2 (1GB memory)
