Got it of a website, they sent my a picture of the CD Key sticker on a Windows CD case.

My assumption is that when a store like Walmart stopped stocking their shelf's with windows 7. So in order to recoup some capital they sold them in bulk. The purchaser is now selling them at a steep discount.

Very responsive OS. I haven't had any issues yet, but I'm unnerved by the amount of tracking that comes with this.

You can use your windows 7 key to activate it... it's also wayyy better than WIndows 8. I prefer it over windows 7 due to the "app" marketplace, and I have a Microsoft account so I like Onedrive and the settings sync between my tablet and PC's.

Could have been better but it's Windows...

This is the flagship operating system - only wished I'd known that I could have downloaded an authentic copy and saved myself about £150 - nevertheless I've got a bona fide version so it's too late to worry about it too much.

I got it for about £2.95 on some crazy Groupon discount. I haven't really used many of the extra features because this is just my gaming rig, but I guess it'll be handy for once this system gets overhauled and turned into my workhorse.

I'm really not a fan of Windows 10, but needs must!

I must say I was hesitant on getting win 10,i got it on the USB stick bc I wasn't planning on installing a optical drive,im going to save the 5.25 slot for maybe a nice fan controller after I add 2 more pull fans to the H100i GTX.but,i really like win 10 much more than win 7 now that ive gotten to learn how to use it and navigate it well,ive read so much bad stuff about it,but I must say it was all untrue in my case,runs all the newer game great,new menu is AWESOME,and its just a good experience as far as my trials with it.

Forays into Windows Server didn't pay off, but hell. Its a Pro key.

It was a gift. I probably would have chosen Home, but Pro is nice to have for the Remote Desktop feature.

Recently I've been liking this OS less and less. Unfortunately this is necessary for a lot of what I do.
