This question already has an answer here:

My Hewlett Packard computer came preinstalled with Windows 7 Home Premium x64. It did not come with a Windows 7 install DVD.

I need to reinstall it because its full of viruses and whatnot.

Can I download the Windows 7 .iso file from digitalriver and use the product key that came in the preinstalled Windows 7 ?

  • @Sparr It worked using the product key from the sticker rather than the one from the preinstalled Windows 7. – elf1986 May 25 '13 at 8:42

It should work if you have the full license key for your Windows license. If you don't have the license key (or can't read it because it's worn off), you're stuck; the remaining information is insufficient to get back your product key. Basically you should write down your product key and store it in a safe place right now because, being on the bottom of your unit, the product key may suffer damage and then you can't reinstall Windows any more.

  • It should work fine but ensure you download the exact same version of the install CD as the product key was intended for. If it was intended for Win7 SP1, then a Win7 CD will not work. Likewise the opposite. – Will.Beninger May 23 '13 at 15:51
  • On my current Thinkpad the license key sticker is inside the battery case - so that it doesn't wear off. – user93353 May 23 '13 at 16:12
