SIRIS, ALTO, and NAS: Limitations of OEM activated machines

Follow

Topic

This article discusses issues involving OEM licenses on virtualized machines.

Environment

  • Datto ALTO
  • Datto SIRIS
  • Datto Cloud Continuity for PCs

Description

Computer manufacturers such as Dell or Lenovo provide Original Equipment Manufacturer (OEM) licenses for the operating system software they contain. This licensing scheme typically ties the hardware configuration of a machine to its Windows product key.

Since a machine virtualized on a Datto device is using virtual hardware provided by a hypervisor, the machine may not recognize the OEM license as valid. Restoring to different hardware from a backup may also cause Windows to prompt you for re-activation for the same reason.

To obtain a temporary or permanent license activation for restored machines, you must call the manufacturer or other provider of the OEM license. Datto is unable to support third-party licensing issues.
