I have an OEM version of Windows 7 running on a Dell laptop, which was recently purchased and I'm unable to locate the Windows 7 key on the laptop or any material included with the laptop. The laptop came with only 2 GB of memory. I'd like to upgrade it to 6 GB, but doing so will require me to reinstall Windows so that I can upgrade to 64 bit. How can I determine the 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
