Windows 7 is quite simply faster, a lot more stable, boots more rapidly, goes to sleep faster, comes rear from sleep faster, manages your data files better and on top of that it's beautiful to look at and easy to utilize. Even the preproduction model of Windows 7 was better than my Vista having SP2.
So let's start with first thing most people can experience - the install procedure. For a long period Microsoft has been attempting to cut down the volume of steps required to set up its operating systems and Windows 7 has stripped the whole thing because of the bare bare minimum.
The whole practice is mercifully simple - slightly longer if you need to upgrade from Vista as opposed to reformat your hard drive (required if you would like switch from XP or the early releases connected with Windows 7). You just select a language, pick a drive to set up on, and that may be it! Go complete a cup of tea and you will be done.
After you get into the actual OS itself, the vital thing that'll strike you is the modern taskbar. It's broader, and the start button not says "Start" onto it, but it functions mostly exactly like it always do with one exemption - the quicklaunch area and the list of running programs are already merged.
