Window 7

www.microsoft.com, duh.

However the download period has ended. You had 6 months to get it free, why did you wait?

The most recent version of Windows 7 that was publicly available was the Release Candidate (RC). The downloads for that ended August 20th. The final version (RTM) is currently available only to those who partner with Microsoft or subscribe to certain programs of theirs (TechNet, etc.). So, if you want to get Win7 (legally*) you have to wait until its general release on October 22nd. Then, you can buy Retail (for build-you-own new computer, w/tech support from MS), OEM (for build-you-own new computer, w/o tech support from MS), or Upgrade (for computer w/previous version of Windows already installed: 2000 [not ME], XP, Vista, Win7 RC).
*Both the RC and RTM milestones of Win7 are available illegally on file-sharing torrents, Pirate Bay, etc., but I can't recommend those. They often come repackaged with viruses, anyway.
Hope this answers your question.

windows 7 rc expires who would want that....

You can buy Win 7 retail technet keys on ebay for $50-$100, each key is good for 10 activations, so if you buy one like that be sure to activate every computer you can up to 10 so the seller cant keep selling the key you just paid for.

Buy a retail key for $50 10 activations, you cant beat that price for a 100% legit activated key!

i'm on technet i don't need ebay!!!!!!!!!!!

Well, I am aware of the license. Thats why mine are not for sale or trade. I'm just saying ebay and ioffer are full of them.

I have used 3 keys, all my own machines. Thanks for worrying about me though, but I;m not stupid. I got my own keys, cause I'm aware the keys on ebay may be blacklisted as soon as MS gets wind. FYI, I even told my represenative about the ebay/ioffer keys.

Hoping MS catches on soon and stops it. Cuttin in on my rigs I sell with no OS and OEM OS.

Thee sooner the Ebay scammers are brought to justice, the better.

50/50 shot of getting blakclisted. For that cheap its better then buying a RC for 10-40.

Besides I cant wait for the scammers to be busted, it hurts the legit sellers alot.

You see legit guys that are powersellers, not moving nothing, then you got these clowns with 1 feedback scamming.

Probably in the long run MS will change the way technet subsriptions and hurt the legit guys there.

I got my sub free and I saved 100s of dollars, and get to use the software now, I couldnt be more happy.

Your probably running RC or RTM cracked with leveno key. Have fun with that.
