    This is general information, please do not take it as "gospel"

    1. Your pre-installed Windows 7 will likely either be a pre-activated installation that employs BIOS modifications and specialized files if it's a machine from so-called "MS Royalty" manufacturers like Dell, HP, Toshiba, etc - OR - uses an input product key which is given on the sticker on your machine.

    Now, my understanding is that all you have to do is reinstall the OS on royalty machines and it's activated during install. BUT don't take my word for it... I haven't thoroughly read and double- and triple-checked this impression like I would if I was going to do such a reinstall.

    2. There are only 2 Windows 7 DVDs: 32-bit and 64-bit. There is a file on the DVD that tells the installer if the DVD is a specific edition or to allow installation of any edition. Now, where to get it? As far as I can tell, it's almost impossible to get a Win7 DVD unless the manufacturer offers ones or you buy a retail or OEM one from a store.

    I'm not sure exactly why it became so hard to get an OS reinstall disk. 10 years ago when I did tech support for Dell, every system shipped with one. But that soon changed and people were expected to restore their machine to "as-shipped" condition by utilizing the hidden recovery partition.

    3. That's an extremely good question. And I strongly suspect the answer is that it might be possible. But rest assured, there are plenty of power-users that have done it. I'm certain good instructions have been posted for both keeping and eliminating the recovery partition, but I hadn't done any research on this myself.

    4. I think it depends upon the licensing model. The "roaylty" machines should be automatically activated or something to that effect. "Product Key" activations have so many on-line activations available (I think it's 4) before you have to do telephone actiavtion. Then there's the various corporate activation schemes like Volume Licensing.

    I hope this helps more than it confuses or at the very least suggests some lines of research.

    I will try to answer all one by one.

    1. OEM systems comes with OS preinstalled and you can find the product key on a label or sticker on the back of your laptop. You can use this key anytime later on if something bad happens. Bear in mind that you cannot use this key on any other machine.
    2. DVD for the Win 7 versions is difficult to get by unless you have MSDN access. You can try getting it from Digital river or use a trial version installer if available from MS. Once again, bear in mind , the version must be same as your original OS that came with new System.
    3. If you do a fresh install, the recovery partition remains intact unless you do something with it. You can do the fresh install without touching that recovery partition.
    4. You can install Win7 OS ,same original one as many times as you like on the same system but with no hardware changes.

    The only 'supported' way to accomplish this is to always install the older OS i.e. Windows XP first.

    That being said, it's still possible to accomplish this.

    Take a look at the following tutorial. Please read the entire article first to get up to speed with the issues and then use Method Two to install XP.



    Keep in mind, if you do something wrong, everything will be lost.

    yes, it does, but you need to save it again as image file

    Where to get the DVD for W& PRO 64-bit

    I already answered it Grr. Only way to get it is through MSDN or digital river or if you can rely on some genuine untouched torrent from a reliable site.

    As I know , you may ask me again to get the links, here are the links from digital river.

    Keep in mind, you need to create ISO from the three files listed on digital river. All the links are legit and you will need a valid and genuine Windows 7 key to use it.

    NO i didn't and perhaps wont. I can only tell it works but you should not attempt in on any working system. Its not for average user or below. If you are a advanced user, you should try otherwise not.

    if you are comfortable playing with your Master boot record and wont have a heart attack when your system gives you just a black DOS screen, if you did something wrong and you can get it back to flashy windows screen without getting a heart attack, you can try it.
