If you are upgrading from one OS to another, you are giving a "upgrade Key" and not actual retail key for installation. Which means that you are entitled from upgrading to Wndows 7 to windows 8 but not to install Windows 8 on a new computer directly.

Hence you need to keep the old win 7 key with you. In the situation, where system is formatted or crashed. you will need to install win7 using old key and then upgrade to win8 using upgrade key.

That is not an "upgrade", but rather a downgrade going from Windows 7 to 8 (at least in my point of view)....

What type of license did you buy for windows 8? As long as it isn't an "upgrade" license, I suggest you use a different way of installation.

1st. way:

Get another HD and remove your current one from the PC, then install Windows 8 to the new one. That way you can put the old disk back in and use your old OS if needed.

2nd way:

Shrink your partition on your current HD using diskmanagement. Then install Windows 8 to the empty space you created. A new boot menu will appear where you can select to which OS you want to boot to.

3rd way:

Install VMware Player inside your current Windows 7 PC. Then install Windows 8 as a Virtual Machine (VM). Now you can start Windows 8 from within Windows 7. Just make sure you have enough RAM in your PC to run both OS's at the same time.

Most PC come pre-installed with an OS from the factory, and those OS's are usually OEM. Also, most such PC's have a recovery partition so you can quickly restore the system to factory defaults. To return such a PC back to factory defaults you normally never have to enter the key for the OS, it is already there. Check the manual for your PC, or online at the manufacturer's site for details how that is done. Apart from that, as most of these PC's aren't delivered with installation media, there is also a utility included that allows you to make one set of recovery DVD for the case that the hard-disk should break down. That should always be done right after having unpacked and run your PC the first time. The problem is that most people ignore this, or don't know about it, or forget to make those media. If you haven't, then again check your manual for details on how those media are created. Do that before starting the installation of Windows 8.

above three methods are only applicable if you have bought new windows 8 license , not an upgrade license ,

I am clarifying of the upgrade license , under this this would only be upgrade media , not the whole windows 8 media , and it should only accept the upgrade keys as explained by  yagyashree

What do you say , A link from microsoft may help answer this question which is already quite clarified by: yagyashree .

If you use an upgrade license, then the old license is not usable anymore. You can only use the old license during recovery, and when the recovery has been done, you will have to run the upgrade again and insert the new key again.

If you do choose to upgrade, you should do a fresh install of Windows 7, add the newest drivers, and then run the upgrade advisor. Finally install Windows 8. Then add your applications.

You are suppposed to be able to upgrade a fully loaded Windows 7 machine to Windows 8, but that has failed for some people.

I went the second hard drive approach and have Windows 8 Pro 64-bit running on a second hard drive. I took the approach that I recommend directly above the upgrade went smoothly.  I also have a Windows 8 preview Virtual Machine which is handy for exploring different Windows 8 features.

Windows 8 is decent for tablets and phones. Windows 7 remain the operating system of choice for desktop computers and regular laptop computers.

so , if I dont want to use windows 8 , and want to revert back to windows 7 , would i have to run recovery and get bcak to windows 7 with win 8 license as you saying windows 7 is no more valid and only win 8 license would be valid as of backward compatibility ???

I know once we have to upgrade windows 2003 server to win 2008 serv , we were given keys which were then even valid for win 2003 as well for the backward compatibility .

please suggest ?

If you have a valid Windows 7 license and install media and if you are definitely not using Windows 8, then you should be able to install it and most likely activate it.

If you have difficulty, you can call Microsoft (Activation and Licensing) and they will help you.

Servers are a bit different in this respect.
