You would need to purchase a valid license for your Windows 8.1 and then activate it using that license - that is the only method we will recommend.

As for your keys, they could just have dirty contacts - try using an aspirator or a can of compressed air to gently blow off dirt stuck underneath the keys.

Another route is update to Windows 10, you will still be unauthorized but could purchase a license for 10 and become Authentic that way.
