Where is my Product Key if I want to re-install?


Like davidhk said. But if you really want to see your windows key, I would suggest Belarc advisor. It will give you some useful information about your system, product keys of your software is among them (not only Microsoft, you will have listed most of your keys).

 

Product key

Hi Megan,

A product key is used when activating a software.
To help us determine the appropriate troubleshooting steps that can resolve your concern, we'd like to ask the following questions:

• What product are you trying to activate?
• Are you looking for the product key to activate your Office application?
• Which version of Office are you trying to activate? To check this, you can perform the steps posted on this
  link.
• Are you looking for the product key to activate your Windows?

We look forward to your response.

 

un block product key

The SPECIFIED PRODUCT KEY BLOCKED error generally indicates a non-legit Product Key.

This may be an error, is the product key original to your PC or did you purchase it online?
