There are lots and lots of blogs and forums who talk about leaked copies of Windows 7 ^[1], however we advise you to beware of those downloads, since many of those installation could be spiced up with a variety of worms, viruses and spywares, that may compromise your privacy and security.

However if you have downloaded a copy of Windows 7 ^[2], before you go ahead and install it, a small tool called Windows 7 ^[2] ISO verifier can save you a lot of trouble.

Once you have downloaded a copy of Windows 7, before you install it, just use this tool to verify the downloaded file, if the file is valid you should see a message saying so.

However if you see a different message it would certainly mean that the installation is gamed to install spywares, malwares, viruses or Trojans, just delete it and wait for Microsoft to release a official version. Thanks Nirmal ^[3].
