No, this is an OEM (original equipment manufacturer) and single use disc for installation on new build. I would also recommend new motherboard and memory if you decide to buy. With 64bit you are not limited to 3GB memory maximum on 32bit systems. I purchased this item because I was dumping all my 32bit windows XP Professional systems and building new 64bit systems with multiple cores and maximum memory. You can reinstall on same computer up to 3 times after that you may have problems activating. Also after install if you change too much of your hardware it will affect your activation. http://www.microsoft.com/licensing/about-licensing/windows7.aspx
Just a consideration... I recently installed Windows 7 (Full Version OEM Home Premimun) on my MacBook Pro Laptop using Parallels software. It installed smoothly with no problems. You might want to read up on Parallels and do a comparison against Bootcamp. I really like Parallels. Windows runs flawlessly and in full screen if I choose to. I boot up in OSX (Mac Operating System), run Parallel's, then select which operating system I want to run with OSX, which in my case is Windows 7 or Unix. To delete Widows 7 operating system, just select it in the Parallels window and select remove! It's gone in seconds. It's that easy! There is no uninstall. Check it out and do what works best for you.
I bought a HP desktop and use this to over-write with it, it didn't work for me(won't format). It required me to have Win 8 OEM to unlock some sort of setting in F8. HP don't included the disk so i did another way... I just bought a Samsung SSD for it. If your situation is like mine, maybe you can do it my way : ) Change from Disk drive to SSD is much faster.
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
