Okay, so this might just be a little rant... so I'm just gonna throw it out here. I've been using Windows Vista x64 Business for a while now. So far, everything's good. However, with all Windows versions I've used, the longer you use it, the slower it gets, even with all the registry defrags, clean up, virus scan, whatnot. So Vista running nicely on my new MBP when I installed it. Fast, quick, very speedy even with Aero. Without doing much, just doing regular weekly maintenance it starts getting SLOWER and SLOWER. Its right now at the point where during boot up, it'll stall for about 1 minute before finishing booting up. Normally, I wouldn't care about a bad OS, i'd just switch to another. However, I actually bought this copy. I paid for this damned OS that won't do what I want without a format every 3 weeks... literally. My company supplied me with a XP Pro disk that I've seriously considering going back to. But that's not the problem. I feel like I got ripped off paying 200 bucks here. It's not I can return the disk or sell it since the CD key's in use and no one would buy it. Even on my new Dell Inspiron 1525 that I've bought for my uncle. He wanted vista, I installed it on there, SO SLOW. The specs aren't bad either, 2.0GHz C2D, 3GB Ram, 250GB HDD. So ya. I'm done ranting. Gonna format back to XP Pro later today.
