Question: Can I use this product to downgrade from Windows 8?
Document: If you're buying this then you should know what you're getting, nothing much to say about it but I used this to downgrade a computer from windows 8 to 7. Most stable and usable version of Windows in my opinion and I've been fixing computers since the days of DOS 6.22. With that said, for myself it's anything but Windows for my use.
After using Windows 8 on my new laptop for awhile it was just too painful to use... So I've decided to purchase Windows 7 to downgrade... Windows 7 is great, it's like a modern/refined version of Windows XP. This is OEM pack but everything installed perfectly. I choose Professional version instead of Home Premium only because I need to do Remote Desktop. Get the 64 bit version so your computer can use memory beyond 3.5gb.
As an IT professional, I recommend Windows 7 Professional to any computer users who are thinking to upgrade from either XP or Vista (or maybe downgrade from Windows 8). The features I really like include:1 - Near-true plug-n-play. All major hardware is automatically configured by themselves as long as a computer is connected to the Internet. In other words, if you fresh install this OS, you better install a network card driver first.
Product arrived quickly. This is windows, so I ought to  1 star it.  ") However, the fact is, the product itself was exactly as advertised and at a good priceTried to get the from a local retailer, they wanted 269. Most folks use their own support. The ONLY difference between this and the one for 100 bucks more is the right to call microsoft.
I'm a Mac user and I had to buy a copy of Windows so I could use it for Internet explorer web testing and also for working from home since my office uses Microsoft.I don't have any issues with the product (except I prefer Mac) but I'd like to point out that this particular product is an OEM (original equipment manufacturer) System builder pack and is intended for system builders. (says in the description and right on the box).
Tried Windows 8 and do not like the single layer screens. Seems 8 was designed for tablets, not desktops. I use 7 for gaming and have no problems. Just wish they'd make IE work better. It is slow!
I tried the 32 bit system and didn't like the limits it put on ram..... I bought the 64 bit and it rocks... Sure it has glitches but they always work them out with updates. If you plan to update to windows 8 then you need 64bit. The professional version gives me the strength of program choices I want and can use..
I am not a huge fan of windows I use Linux on most of my desktops and Unix on my servers but I do have to have windows for some applications. I would rather have windows 7 than windows 8 any day. This is by far the best windows for me, I really hate windows 8 and remove it as soon as I can  and install windows 7. It is must have for me.
I use Windows out of necessity because I'm so invested in Windows based software. Otherwise, I'd have a Mac. This version for me, has proven to be very stable. So much so I definitely will not be moving to Windows 8. Given past frustrations with Windows OS, I'm amazed to find myself saying this one has never once caused me any problems. Not once in the 4+ years I've used it.
Hopefully MS can fix most of the annoyances with 8.1 when it comes out, but till then I'm sticking with 7. Sure 8 has some new features that I like, but for every 1 thing they made better they seem to have made 8 backwards steps elsewhere. Windows 7 has proven itself and works with all the applications I use and support so I see no reason to deal with windows 8.
Answer: Yes 100% yes, I personally did it. However be prepared youtube has may videos on how and why just be prepared to mess with the drivers for your computer and the bios. Also tech support  with almost disown you -source personal experience
