How do I get a Microsoft Software Activation key for software I have licensed through the Microsoft Select Agreement?

You may need to request a software activation key for volume licensed Microsoft software. Details can be found at the Obtaining a Microsoft Volume License Key page.

Official activation may not be suitable for some reason and then you need to use a third-party solution. It is convenient and you do not need to worry that after some time you will need a new key.

Here you need to bypass the use of the activation key and the best option would be to use kms activation which is easy to set up and does not require entering individual keys for each installation. The program can activate the server, which will be responsible for all licenses, which saves time and nerves when activating multiple copies of programs.
