Mandatory Server Upkeep

This page only applies to Windows servers running an evaluation version of Windows Server which includes most virtual & bare metal servers.

If you see a message in the bottom-right corner of your desktop similar to:

Windows Server 2019 Datacenter Evaluation

Windows License Valid for X Days

then your server must be rearmed every 180 days. Follow the instructions below. If you do not see this message, no action is required.

What Happens If I Don’t Rearm?

If the Windows evaluation license expires:

  • Windows may begin shutting down automatically.
  • You lose access to your server
  • A support ticket will be required for our team to manually restore access and perform the rearm process which will take time.

Virtual Servers Only
This does not apply to Bare Metal Servers

If server is not re-armed before windows license expires, it will shut down and you will need to open a support ticket so our team can manually reboot it and re-arm it for you.
