Microsoft announces Windows Server Insider Preview Build 17046

It was only a couple weeks ago that Microsoft announced that Windows 10 build 17046 was available to those on the Fast ring. Now, the firm has also announced the arrival of the Windows Server Insider Preview Build 17046.

The build marks the second preview and like any Insider build, there are known issues with it which can be seen down below.

  • [NEW] Dynamic disks fail I/O with STATUS_INVALID_DEVICE_REQUEST, resulting in failures to mount or format a volume. The contents of an affected volume will be available after updating to a build that fixes this issue, so reformatting and restoring data from backup is not necessary.
  • Upgrading to recent pre-release builds of Windows Server is not currently an option. However, upgrading will be supported in the future.
  • The Health Attestation CSP fails with error message 500 when attempting to get a certificate.
  • Data corruption may occur on some NVM Express (NVMe) solid-state drives (SSD) if scatter-gather list (SGL) functionality is enabled.
  • The base filtering engine (BFE) service may fail to start, which prevents the Windows Defender firewall (MpsSvc service) from starting.
  • A system crash may occur because of a kernel security check failure (bug check 0x139) from a corrupt list entry in a deferred free pool.
  • Hyper-V isolated containers will fail to start with an error of “The description string for parameter reference (%1) could not be found. (0x3ab6)”. Users can work around this by temporarily disabling our cloning optimization by creating a registry key and rebooting or restarting the vmcompute service.
  • reg ADD “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Containers” /v TemplateVmCount /t REG_DWORD /d 0

If interested, you can register as an Insider, and head to the Windows Server Insider Preview download page where it will be available as a Server Core Edition in ISO or VHDX format. Per usual the team would appreciate the feedback, which can be left in the Feedback Hub application. The Windows Server Insider Preview Build will expire on July 2, 2018.
