モートデスクトップサービスの評価期間について

There seems to be no public information on why the number of days of 120 days is decided, but by setting a grace period, you can check the number of licenses and license modes (user license / device license) actually required, so I think that the purpose is that you can build a license server smoothly. The idea would be that 120 days is enough for such a verification.

120日という日数がどのような理由で決められているのかの公開情報は無さそうですが、猶予期間を設けることで実際に必要となるライセンス数やライセンス モード（ユーザーライセンス/デバイスライセンス) の確認ができるので、スムーズにライセンスサーバー構築が行えるという趣旨だと思います。そのような検証には 120 日あれば十分という考え方でしょう。
