I bought a refurbished tower with windows 10 pro on it and I need a product key to activate windows 10 pro.

it says I have a "Current Product key: *****-#####".

Looks similar to this:

 "Product Key: XXXXX-XXXX-XXXXX-XXXXX-XXXXX".

I've never seen this product key anywhere. only the one sheet of paper that's was in the box was accidently thrown away before I could see what it was. 

I have a great idea and I want Microsoft to be apart of it. How should I continue in this process?

How can I get my side bar for signing off control panel , to sign of etc.

Every time i open League Of Legends it opens a little tab or folder or whatever you call it with the name ''RADS error'' and then its says: 'Unspecified error occurred. Please check the logs for more information'' . I did check the launcher logs but nothing seemed severe. I don't know what the problem is... Also, why does it make me search for a product and topic, since there is nothing that i am concirned in those. Maybe you should just add a 'Other' note.
