I have an OEM version of Windows 7 running on a recently purchased Dell laptop. The laptop came with only 2 GB of memory but I'd like to upgrade it to 6 GB. To do so will require me to reinstall Windows so that I can upgrade to the 64-bit version.

I'm unable to locate the Windows 7 key on the laptop or any material included with the laptop. How can I determine the product key used to activate Windows on my machine?

Update: Is it the Product ID located under the following (Paste into Windows Explorer)?

Control Panel\System and Security\System

Power down the laptop and remove the battery, you should find it on the case, safely hidden away... ;-)

On the command line ("cmd" in run interface in start menu) type

slmgr.vbs /dli

and wait a few seconds, a popup will appear with your serial number in it.

It will give the last five characters of your serial number if your on a OEM license, otherwise (basically for retail and volume licenses) you will get the whole serial number.

There is a very nice program called Belarc Advisor which is free for personal use that will tell you many things about the state of your Windows PC including all the Microsoft activation codes in use.

I was interested in the answer to this question myself so did a quick google.

Found the following website which may be useful.

I can't verify for sure whether it works nor whether the tools page the article links to is trustworthy but it seems to answer your question.

Hope this helps.

Magic Jellybean Keyfinder is the best out there.

Being a Dell laptop it should have an OEM licensing sticker on the machine somewhere. Possibly under the battery, or just on the back of the machine.
