"My System Wasn't Up To Speed"
I'm sorry I didn't listen when I was advised to wait until I purchased a new PC. For Windows Vista, your system may lack resources. Though it will run, it runs much slower. At least with Windows XP, I could play my movies on DVD. My video card was not up to snuff for Windows Vista. I had driver problems but finally got the right ones. I found I was happier with Windows XP, so I went back to it.

"Don't waste your money"
As an expert computer user, (started with DOS) I would have to say that this is the worst piece of junk conceived by man. I would give it zero stars if I could. DO NOT down grade your computer with this junk. You will pull your hair out installing it. It will crash. It is much slower than XP. It takes forever to boot. And You Will Be Sorry!!!!!!!! Bill gates will laugh all the way to the bank with your money. The clowns in Redmond WA finally drove me to buy a MAC, and I could not be more pleased with OS X. I hope that this is the beginning of the end for Microjunk.

"Satisfied"
I originally ordered this mostly because I wanted to play Halo 2, which I had also purchased. Despite the many bad reviews this has received, I bought it as I am a Halo fan and really wanted to play it. I made sure to use the windows vista upgrade advisor before purchasing it as I didn't want to end up with something I couldn't even use. The Microsoft upgrade advisor also tells you which version of Vista you should get. Those of you thinking about purchasing Vista as well should use the advisor before purchasing it, and you can find the advisor at the following site: [...]

So far I am quite satisfied with it (I am not entirely used to the new layout yet, it will take a while, but I am definitely getting there). the install time wasn't too long (took about an hour or so, possibly less but I wasn't timing it). I was able to use the "in place upgrade" option as I had the XP media center edition. I am not entirely sure if the clean install takes longer or less time as I did not do that option.

So far I have not run into very many problems with this, and the ones I do run into have been VERY minor. Someone mentioned that i-tunes doesn't work with this and that is false. You merely need to go to the add/remove programs and select the repair option. The add/remove programs is found in the control panel under the programs section.

The one thing I do dislike about Vista however is that there is a pop-up that comes up a LOT asking if a program should be allowed to run or not. There might be a way to make Vista stop asking permission to run everything, but I don't mind it enough to go looking for one.
Aside from this slight annoyance (which may be more or less annoying to you) and a few other very minor issues, I am glad I purchased this. Overall i am giving Vista a 4 star rating.

"Expert Windows User - Vista is Terrible"
I have been using IBM since the days of DOS, and Windows from the very beginning. There is no question that this is the absolutely worst version yet of any Windows / Microsoft product. It is literally as if they went through every single element of operation and made it much worse than previous versions. What the ....?! I had NO choice but to receive "Vista" from Lenovo when I ordered my laptop. I did not want it. I had already seen the bad reviews EVERYWHERE. However, as I said, Lenovo/IBM gave me no choice of software. Did someone say communist dictatorship? I am very, very knowledgeable regarding Windows software. I have NEVER needed assistance to fix a problem or do anything whatsoever that I wanted to do. I gave this new "Vista" several months. I will now be forced to pay full price for a new copy of XP, just to throw away Vista which I was forced to pay for by Lenovo (most other companies are also forcing Vista). Utterly terrible. In every possible way, the worst Windows OS yet. And, as far as I can gather, the only solution is to buy a MAC instead.

"Windows ME for a new generation"
Windows Vista was rushed out way before they could work all the kinks out. As a result we get driver problems, incompatible software, countless BSODs (blue screens of death), operating system crashes, a butt-ugly GUI which requires twice as much memory as you currently have, UAC (user account control) which makes you click through several prompts to install software, a buggy browser in IE7, annoying WGA nag screens, and last but not least: there are five different incarnations of the operating system and they're all too bloody expensive.

Stick with Windows XP and wait for Windows 7 in 2009!
