On March 15, 2022,

Windows 2016 hosted runners will be removed from GitHub Actions. In preparation for the deprecation, there are two scheduled brownout periods for our team to perform maintenance:
December 1, 2021: 4:00pm–10:00pm UTC
February 7, 2022: 4:00pm–10:00pm UTC

Jobs that use Windows 2016 scheduled to run during this time will temporarily fail.

What you need to do

We recommend you change jobs using runs-on: windows-2016 to use runs-on: windows-latest which will ensure you're always running on the latest version of Windows Server.
