If you don't have a stable XP/Vista/Win7 you are doing something wrong. People imo act as if Win7 is the only thing stable out there.
As one person simply put it, someone come out with something that is so good that makes me run to the store, like video cards used to. We've been sideways with game innovation for a few years now. That isn't my problem.
FWIW I use ObjectBlocks from Stardock so my UI is completely something else then what the quirks at MS come up with. I wouldn't have to worry about Win 7's Start Bar, I simply make something better myself with Objdocks.
Another person mentioned gov't back-doors. Each new version of Windows keeps taking admin rights away from the admin, bs. They think I don't really have the right to have total control of my own system. Pretty shitty searching say the whole C drive, but the O/S doesn't count several hidden locations and the list on where it won't look just gets bigger and bigger. You know it's because of their paranoid view of DRM. But my searches have nothing to do with that. But they treat me that way.
Or how install/uninstall/temp files get clustered and many never are removed anymore and how that just eats up HD space. Look my HD is full, how can this be? I don't know, let me google somethings. OMG they just put this new wizbang feature in the OS to embed these files deep within directories and they never really get removed. Why Gov't? Phising? HD mfg back scratching? Why can't I say uninstall and it's gone anymore? No wonder my HD's are full. So how do I get rid of them? Go to a Command prompt, run a geek line of code to switch file or policies and wala, now I can have my Win7 give me the control I always had in XP.
My Quad XP system is no less stable or slower then my Vista or my Dad's 7. From what I've seen the Dx10/11 stuff means very little. When I'm playing I can't see that minuscule shadow improvement between the dx versions, because I'm busy playing. So imo the games look just as swell to. Or should I just give MS $150 per system for the hell of it? I say give me a reason to run to the store.
