Reinstalling Windows 7 Home Premium

Hello everyone. I've recently built a new computer and reused my old HDD. I didn't have the windows disk to re-install, so I burned a windows 7 iso to a disk and re-stalled windows that way. Well, the problem is I just got a notification saying the key I used was wrong, and after checking, I realized I'm running the 32 bit version, not the 64-bit which is what the key was for. So, my question is, after burning another Windows 7 home premium disk, what steps do I have to take to install it. I need specifics such as whether or not I will have to re-install my mobo and gpu drivers, etc. Thanks!

    With any type of reinstall (unless it's an OEM version) you will have to reinstall most of the hardware drivers onto the computer. If the previous version of Windows that was installed on your old HDD was an OEM copy then the product key and activation are tied to your old motherboard and not the new one.

    Long story short, you will have to purchase a new product key/software to be used with the new MB if the previous copy was indeed OEM.

  2. OEM versions of Windows 7 are identical to Full License Retail versions except for the following:

    - OEM versions do not offer any free Microsoft direct support from Microsoft support personnel

    - OEM licenses are tied to the very first computer you install and activate it on

    - OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard

    - OEM versions cannot be used to directly upgrade from an older Windows operating system ^

    OEM vs. Retail

    OEM Windows 7 comes preinstalled on computers. This is the cheapest way to buy windows. Large PC manufacturers like Dell, HP etc. (collectively called royalty OEMs) install windows on millions of such PCs. The main characteristics of such systems are:

    The license agreement and support agreement is between you and the PC maker, not MS.

    Activation by the end user is not required. Windows is preactivated at the factory by the OEM using images and standard SLP keys.

    Your copy of windows is locked to that PC. The license is not transferable.

    OEM system builder is what you get when you buy from say Newegg or from a local "white box" vendor. It too has the characteristics of Royalty OEM windows. Although it is possible for an individual to buy a System Builder copy, the license requires that the software be installed using the OPK (OEM preinstall kit) and then resold.

    Retail version is what you buy from a retailer like Amazon or Bestbuy. Its a full price version that comes packaged in a retail box with a retail product key. It has to be activated online via MS servers using the key on the box, it is not tied to the PC it was first installed on, though it can only be used on a single computer at a time. And, MS directly provides the support for it. It is also more expensive than OEM copies.

    As far as functionality is concerned, theres no difference between any of the versions above, given any specific edition (i.e. between OEM pro and retail pro, or between OEM ultimate and retail ultimate).

    Windows 8 OEM is a whole different ballgame.

  3. OEM keys are not 32 bit and 64 bit specific.........the key would work for both if it was legit........
