Windows 7 Media player will not play back BluRay disc's

Ok Just to let everyone know I'm just a average computer user with perhaps basic to intermediate technical knowledge of computers, but I'm very sure of one thing I'm upset that windows 7 does not support blu ray play back. I bought my Sony Vaios last year and the one major incentive I had for purchasing it was the blu ray play back capability that it had advertise so vehemently. Now I did not care that it came with vista which I heard horrible, horrible things about all I cared about was watching my blu ray movies on my computer, but to the contrary vista worked fantastic for me and I loved it and loved watching all my Bbu ray movies right on my computer without a single problem, fast forward a couple of months and behold windows 7 which was supposed to be an "upgrade" from vista, (and I use the term loosely) so hey I figured if vista was good windows 7 was definitely a must have. So silly me I jump on the chance to get the free "upgrade" to windows 7 that Microsoft so generously offered. Suffice it to say that I wish I would have just stayed with vista. Now how many of you have heard anyone say that? smh at myself and Microsoft. Now I'm force to spend 70 -100 dollars on third party player. Not a good look during this recession. But hey I'm over it I guess....Not. And yes I know there are alternatives but I wanted to watch movies on my computer thats what I originally paid for and now I guess I got to pay for it again.

dont pay for the third party software, microsoft could be in partnership with there "recommended" software, dont do it, rip them off the way they rip us off, hack the ____ out windows 7, (very easily done) download nero 10 or cyberlink dvd, get the torrents dont buy them. and NEVER buy windows operating systems again. always wait till a hack or patch comes out for them. microsoft install dvds already have the "key" on the disc, you just have to find a way of extracting that file and taking the key. thats all your realy paying for, a stupid key. there is ways of doing it. just look hard enough and you will find how. as for blu-ray on windows 7, if they did bring out a blu-ray add-on for wmp then it would probably just end up being a huge joke, just like w7 is. microsoft are the biggest joke though, all these years of "experiance" going on about how good xp was, then vista, then w7, and they cant even bring out a silly add on. lol, i seriously dont know why we continue to support and buy there software, windows is the easiest to get infected by viruses etc, if you had the know how, you could reprogram windows 7, dismantle the full dvd, and rebuild it, like we have done with xp. only thing stopping us doing it with w7 is theres far to much data to rebuild. would take months. just do as i said above and you will be fine. you will get your blu-ray playback

Guys, this is getting rediculous.. 

1. Firstly, how many people are ACTUALLY using Blu-Ray on their computer? Only a very small proportion of people (I know, I work at a computer store, and despite the price drops on drive, we still don't sell that many blu-ray drives). Are you telling me that Microsoft should pay a huge fee for each copy of Windows to Sony, whilst very few people actually use Blu-Ray? 
2. How many people actually buy Blu-Ray movies. Lets face it, very few. Digital downloads is the future. We all know that, so why the outrage? Why give MORE power to the companies who are trying to kill digital distribution
3. Blu-Ray as a format is so unfriendly to consumers that MANY people need to hack it to make it work, even after paying the licensing fee. This ignores the fact that your display manufacturer also needs to pay a licensing fee.  Most people still seem to be using DVI, and most displays only ship a DVI cable in the box. Blu-Ray is so anti-consumer that if Microsoft included a codec, they would need to support it, and customers don't accept "your hardware isn't appropriate" as an answer. 
4. Sony as a corporation is corrupt. They placed rootkits on their CD's, and now you guys are banging your drums encouraging their dominance. I'm sorry, but NOTHING Microsoft has done, can ever be worse than Sony.
5. Sony have the power to prevent newer disks playing in compromised implementations. The problem is that ANYTHING can be cracked, and Microsoft is such a nice target, so we can almost assume that Sony will try to break support 24/7.  

You guys need to think long and hard about this.  It doesn't make sense for Microsoft to do this financially, it doesn't make sense for non-blu-ray users, it doesn't make sense to anyone who wants digital distribution to take over, and it doesn't make sense to anyone who wants to be able to one day click their movie online and stream it for a few sense (because Sony is doing their best to prevent that happening). It's very short sighted to force everyone to cough up a massive Blu-ray Tax for a standard, because Sony once again decided to fragment the industry again. 

And the anti-Microsoft stuff I'm hearing here is a JOKE. Some of you guys need your brains examined (seriously). There is NO WAY, I'm paying a few dollars for a Blu-Ray codec to Sony and a few cents tribute for every disc sold whilst Sony also have the power to flip a kill switch (and steal my money). Seriously, I don't agree with Steve Jobs much, but Blu-Ray is a bag of hurt, and you'd have to be a total moron to wage some holy war against Microsoft in Sony's name.

HD DVD may have died, but it was still as bad as Blu-Ray anyway. Instead, wage a holy war against optical media, and try to get studio's to release movies digitally (so that everyone wins). Microsoft are actually pushing digital downloads more anyway (so in some ways they are on our side).

@AndrewLuecke Talk for yourself but it's preposterous to assume nobody else watches Blu-ray discs:

1. Millions of Blu-ray discs have been sold already, it's a 2 billions dollars business, sales were up 75% this year, 13% of U.S. households have a Blu-ray player, Avatar alone sold 1.5 millions BDs on the first day. If you had read this thread, you would have seen that we are not asking Microsoft to pay Sony and give us Blu-ray for free, but that customers pay for it as part of the premium in the Ultimate edition of Windows 7. Not every copy of Windows, only for those who pay extra because they need Blu-ray and they'd rather have it integrated into WMP/WMC than being forced to research which third-party player works well and purchase it separately.
2. Digital downloads are a joke, it's nowhere near the quality of a Blu-ray disc, does not include a choice of audio and subtitle tracks and the extras, the choice of available titles is not a thousandth of the titles available on DVD or BD, and it's split between many different providers if you really want all the titles available online. I actually never play the physical BD on my computer, the BD is used only once to rip the disc (the full 40 GB or so), then I play it from my media library to my computer or to my TV.
3. I have had no problem whatsoever with Blu-ray on either my computer or standalone player.
4. I agree about Sony, it's just another bad Apple (iTunes). Still, if you want to watch HD movies, there is no choice other than BD, so we are in this captive market whether we want it or not. I believe the license fee mess is the only reason why Blu-ray is not as prevalent as it should have been by now, I hope the fee for the players will be removed in a few years. I don't understand how Sony and the other BD licensees were able to create such a monopoly when we have all these laws against monopolies and trusts. It is just not acceptable that something as important as HD movies require such an expensive setup and that Sony competitors are forced to pay Sony for it.
5. I have no idea what you mean, existing encryption keys can't be revoked, it would make hundreds of valid titles unplayable.
