NOTE: There is a similar system for Office 365 activation but that requires to redeem keys at an MSFT page. The keys MS hands out are all stored at the activation server, same as all Windows Retai, MAKl and OEM keys (no way to generate valid keys). For that reason this cannot be mimicked.
KMS is the only option then.
