It is just like any other Windows.
However, don't install rubbish etc... and it will be as good as the day you install it.
This is a true story -...
I went to a local shop that called me out to "do up" all their computers, they had 6 Windows machines and 2 Macs, they were saying that they are going to get all new Macs soon... I said why and like you they said "We have had the Windows PCs for about 4 years, they are slow and we hate them".
Long story short, Their Windows machines were being used by the staff in every break for internet, porn and other stuff - had advert bars, tons of useless programs (Smiley central...), about 5-6 different monitoring programs for digital cameras that they had at one point and never removed...Where as their Macs in the same 4 years ONLY had photoshop installed as they did not let staff use them in breaks.
I pointed this out to them, and said, if you treated the Windows machines in the same way, they would be just as good
This is just telling you the start of it.... but I hope it gets the point across - it is not just the operating system, it is how you use it.
