Where do I find the Windows 8 product key when it was preinstalled on a Samsung Laptop?

Here are four utilities, all of which will may display your product keys if they are still there:

(It does a good job of providing a wealth of information.)

and RockXP: http://www.majorgeeks.com/download4138.html which has additional features

You have a couple options:

If you would like to reinstall Windows 8, which means removing apps and personal files and settings, you can use reset and refresh. This is equivalent to a clean install.

To do it, do the following:

· Press Windows key + i on your keyboard to show the Charms bar (If you are using a touchscreen: Touch the right edge of your screen and swipe your finger to the left)

· Click Settings

· Click Change PC settings

· Click General in the left column

· Under Remove everything and reinstall Windows, click Get started

Then follow the instructions that will be provided on the screen to reinstall Windows on your PC.

Option 2:

If you create a installation DVD or Bootable thumbdrive, you can use that to reinstall Windows. First, you will need to reinstall the qualifying license, then start the upgrade again to Windows 8. Qualifying license means you will either need to reinstall Windows XP, Vista or Windows 7.

Option 3:

A workaround for this situation is to create a system image of Windows 8 just after you have upgraded. So if your drive does crash, you can simply restore the image on a new hard disk or restore the image on the same drive if you just want to reinstall Windos 8.

See the following for instructions about how to create a system image of your Windows 8 installation:

(references Windows 7, but the same principles apply to Windows 8).

. One of the improvements Microsoft is making to Activation 3.0 for newly built machines that come preloaded with Windows 8, you won’t have a COA (Certificate of Authenticity) sticker attached to the machine anymore. Instead, this will be embedded in the BIOS. This will avoid product keys from being compromised and OEMs will buy what they need.
