### Issue:
Started: December, 2019.
Packer cannot connect with WinRM to machines provisioned from Windows 2016 (2016-Datacenter) Marketplace image in Azure.

### Further details:
WinRM timeout increase is not working. It seems the last image working is version: "14393.3326.1911120150" (Released 12th of Nov). It stopped working with "14393.3384.1912042333" (Released 10th of Dec).

This issue is only impacting 2016-Datacenter. 2019 is working properly.

### To get image Details for a Region:
az vm image list --location northeurope --offer WindowsServer --publisher MicrosoftWindowsServer --sku 2016-Datacenter --all

### URL to the Last Working Image:
https://support.microsoft.com/en-us/help/4525236/windows-10-update-kb4525236

### URL to the Image where something went wrong:
https://support.microsoft.com/en-us/help/4530689/windows-10-update-kb4530689

### Notes:
This is currently applying to North EU. I had no time to investigate in other regions but I believe the same images getting distributed to every region.

**I am opening a Microsoft case and planning to update the thread with the progress.**

Start by running the provided az vm image list command for the affected region and comparing the last working and failing Windows 2016-Datacenter image versions. Review the linked Azure documentation issue and the comment thread for evidence of the WinRM failure; done would require identifying a concrete plugin-side change or confirming that the problem is external to Packer.
