Upgrading your Windows operating system or moving to a premium edition often requires specialized utility software or dedicated activation pathways. If you are using a Windows upgrade helper tool, a licensing assistant, or a custom system deployment environment (frequently referred to inside IT circles and software utilities under terms like "Upgrade Mate"), managing your license key correctly is vital to ensuring your operating system remains genuine, secure, and fully functional.

Alternate way to submit your public key to the key servers using the CLI

gpg --keyid-format LONG --list-keys john@example.com
pub   rsa4096/ABCDEF0123456789 2018-01-01 [SCEA] [expires: 2021-01-01]
      ABCDEF0123456789ABCDEF0123456789
uid              [ ultimate ] John Doe <john@example.com>

This shows the 16-byte Key-ID right after the key-type and key-size. In this example it's the highlighted part of this line:

pub rsa4096/ABCDEF0123456789 2018-01-01 [SCEA] [expires: 2021-01-01]

The next step is to use this Key-ID to send it to the keyserver, in our case the MIT one.

gpg --keyserver keyserver.ubuntu.com --send-keys ABCDEF0123456789

Congratulations, you published your public key.

Please allow a couple of minutes for the servers to replicate that information before starting to use the key.

General notes on Security

A keyserver does not make any claims about authenticity. It merely provides an automated means to get a public key based on its ID. It's up to the user to decide whether the result is to be trusted, as in whether or not to import the public key to the local chain. Do not blindly import a key but at least verify its fingerprint. The phar.io fingerprint information can be found in the footer.
Instead of using a keyserver, public keys can of course also be imported directly. Linux distributions for example do that by providing their keys in release-packages or the base OS installation image. Phive will only contact a keyserver in case the key used for signing is not already known, a.k.a can not be found in the local chain.
