Well, I have to disagree. The more I use Vista, the more I'm hating it. I really wish I had sought out an older model with XP on it.
Firefox crashes about twice a day. I never had a Firefox crash in XP.
Windows Media Player is apparently not available in Vista. To get Firefox to use WMP you have to manually copy some XP DLL into your program directory.
I have two ISP's both of which provide free virus protection software. Neither package will install on Vista.
At least one game which ran fine on XP will not run on Vista. No surprise really, but Vista offers me no features that I care about more than that game.
It's very slow.
In order to run a program you have to confirm as many as three times, and quite often the program still doesn't run (ref. my anti-virus packages).
Benign start-up programs like Adobe update manager are blocked, and there is apparently no way to unblock them.
The supposed help for all these problems is useless.
I frequently get messages that say "Such and Such a program may not have installed correctly! Would you like to reinstall? When I click on help I get a message that has nothing to do with installation.
I don't recommend it. Period.
My experience has been just the opposite. I installed Vista a while ago, and I'm liking it more and more as I become more familiar with it. I've had no unexpected crashes since installing, in fact it seemed to stabilize some games I couldn't get to run in XP, such as Dark Messiah (still runs like crap going down to 30 fps on my 8800 GTX, but it at least runs without crashing now which is better than on XP). My fps seem a bit lower overall on Vista compared to the same game (expect Dark Messiah) while on XP, but I can't really notice the change. Not much of a difference between 140 fps in WoW and 115 to 125, and the slower frame rate is more than made up for in my opinion by the faster load times I seem to have. I have noticed some small glitches, but I was aware of them since the driver notes for my vid card documented them as still needing work. Such as my monitor not being initiated again after Vista goes into sleep mode, and I suspected this will be fixed within the next few driver releases.
As for foxfire, I'm on it right now typing (still don't like IE

), and I haven't seen it crash once for me yet. Windows media player works just fine for me, in fact it has features I didn't get in XP. My media player in XP wouldn't do 5.1 surround for me when watching DVDs, I had to use NVDVD instead. In Vista the 5.1 works just fine without me having to change anything in the program, just pick 5.1 from the DVD's audio menu if it isn't the default.
For your problem with startup programs being blocked, you have to open the control panel from the start up menu. I normally change it to classic view over on the left here, then you head down to Windows Defender. Hit the tools button up on top then open software explorer. There is a drop down menu towards the center of the screen, it should default to startup programs, but you can choose to look at running program or services as well. On the bottom left it lists all the programs that are set to start on startup, I normally right click there and group by startup type. This tells you where they're located to start up, either registry entries or in startup folders, etc. It also lists the categories here, such as permitted, not yet classified, or disabled. Permitted and disabled are pretty self explanatory, and not yet classified means that windows defender isn't sure about the program but it is still permitted. At least, that seems to be the way mine is set up, programs like my nvidia control panel, and steam are listed as "not yet classified" but they start up when I boot the computer. If adobe isn't starting for you, check to make sure it isn't disabled here, or it might not be compatible with Vista and unable to start. I have adobe reader 8 and it seems to work fine. Hopefully this will help.
I sure feel like I'm in the minority sometimes, being a person that had a smooth transition over to Vista. There are a few things that get annoying, like many programs for configuring your computer pop up windows asking if you want to proceed... a lot. Also, learning an almost completely new layout for windows took some getting used to. Many of the ways of configuring window components seemed to have changed quite a bit, but for the most part, I'd have to say my experience with Vista has been positive.
ETA - Learned something new... again. Seems that windows defender is put towards the top of your all programs menu in the start menu. Just noticed this, I had been going the long way.
