You look at your retail package and see the usual hologram and more. Microsoft knows about some fake retail packages out there and will help you for free verify if yours is fake. For your trouble, if it is fake they have been known to replace it IF you work with them to supply them with where you got it and give them the fake products.
-> There is also a lot of malware that will damage the OS and cause validation failures. But there is nothing in your post about that or torrent use.

This morning I started my PC to discover that it told me I have a illegal copy of Windows 7 on my PC, funny thing is *I* own a retail version of Windows 7 home premium, so I restored the PC thru safe mode
and when it came up, I found *ALL* my security software shutdown, and not current. Including Windows Defender, and Windows Firewall was shutdown, as well as my other firewall. NOW I'm wondering if this so-called retail version of Windows 7 is truely legit.
