企业内网的Windows 11虚拟机需要使用KMS服务器激活，并且用户可以远程登录使用windows虚拟机。用户需要购买哪些许可，通过什么协议来下单？

Hello,

Thank you for posting question on Microsoft Windows Forum!

Based on your above queries. Well! For license type. Since you are activating Windows virtual machines via an internal KMS server, this indicates that you are using Volume Licensing. Specifically, the Windows Enterprise Volume License (often part of Microsoft Volume Licensing programs such as Microsoft Enterprise Agreement (EA) or Microsoft Open Value Subscription) is required. KMS (Key Management Service) activation is only available with Volume License editions of Windows such as Windows Enterprise, Windows Professional VL. Retail or OEM licenses cannot be activated through KMS.

Regarding the agreement to place the order. To legally obtain and use KMS activation, your organization must have a Microsoft Volume Licensing Agreement in place. There are three most common agreements. 1/ Enterprise Agreement (EA) which is for large organizations, covering Windows, Office, and other Microsoft products with centralized management. 2/ Select Plus Agreement which is for flexible option for midsize/large enterprises and 3/ Open Value Agreement which is designed for smaller organizations, subscription-based. In practice, most enterprises use the Enterprise Agreement (EA) because it includes rights to deploy Windows Enterprise editions in virtualized environments and supports KMS activation.

For Remote Login Requirement. Actually, remote login to Windows virtual machines is supported under these licenses, provided the organization complies with Microsoft’s Virtual Desktop Access (VDA) rights. If users are connecting remotely (e.g., via RDP or VDI solutions), licensing must also cover Windows VDA rights or Software Assurance (SA) which are typically bundled in the Enterprise Agreement.

是否有推荐的产品的SKU。如果分批次购买，第一次买300个能否用EA协议，如不能，使用Select Plus协议购买了第一批，以后能否转成EA，并用EA采购更多的许可
