Leaseweb strives to make any new stable/production release available as fast as possible. However, due to the large variety of hardware that we offer, new releases may not immediately be available at LeaseWeb at launch time. If you need to run a specific OS version, you can always request this as a custom installation.

Microsoft Windows Server - Windows SPLA 

The Service Provider License Agreement (SPLA) program is specially designed by Microsoft to deliver a simple solution to all service providers who would like to offer software as a service.

SPLA provides 3rd party commercial use rights to service providers, who will be the holder of the Microsoft licences, so that end-client (you) receiving services deployed on Microsoft Software Products are not required to obtain their own Microsoft Software Licences.

You receive the right to interact with Microsoft software functionalities through the  SPLA licences provided by Leaseweb.


We currently offer the following Windows Server editions (64-bits only):

  • Windows Server 2022 Datacenter
  • Windows Server 2022 Standard
  • Windows Server 2019 Datacenter
  • Windows Server 2019 Standard
  • Windows Server 2016 Datacenter
  • Windows Server 2016 Standard
  • Windows Server 2012 R2 Datacenter
  • Windows Server 2012 R2 Standard

The following Windows 2012 editions are only supported for existing deployments and can no longer be ordered on the Leaseweb.com website or in the Leaseweb Customer Portal:

  • Windows Server 2012 Datacenter
  • Windows Server 2012 Standard

See also Microsoft - Product lifecycle for Windows Server

For in-depth information on the differences of the editions, we would like to refer to the SPLA overview as provided on Microsoft's website: Get started with Microsoft SPLA Licensing


Leaseweb does not support End-of-Life versions of Windows, e.g. Windows 2003, as these are not supported by Microsoft anymore.

Additional Microsoft applications

Terminal services

Besides the amount of users that is included in the SPLA edition, we can assign additional Terminal licenses to the Windows license.
