Why are you doing this to me? Tell me WHY??!!! how do i know if the Windows i purchase every time is genuine or not? this is ridiculous and i suspect that is another trick from you for more profit as all megacorps besides. I purchased Windows XP Pro SP2 from the shop where i purchased my pc, and is from the most reliable shops in my town, do you believe that would sell illegal software? now you suggest me to purchase a validation key in order to be able to install microsoft related programms as Defender and WMP 11, but i have paid already too much for the Windows i purchased and you ask me to paid two times for it? please have mercy on me, i'm suffering from quadriplegia and this is the only entairtainment i have in life and with all this you are throwing before me borders making my life a hell and so miserable with the allegedly validations of the product. I wish Mr Gates could read this and do something to change all this policy of Microsoft. It's a shame what you do on me that so helpless to cope up with all these.
