Re: Steam Error
You won't miss the free spyware and viruses that come with the platform either. Windows applications are pretty horrid and no wonder Windows gets clogged.
Six is right, it happens all the time but just because it might not happen to you, don't mean it doesn't happen to the rest of the world.
Unless you know your applications and where to get them from via a trustworthy source, you can get into big trouble. Mind you, I hardly have anything installed, except game related things and probably way Windows 7 is running well.
BTW, I had a similar issue with Stream on Windows 7.
