This Server Insider pre-release build will expire on July 2nd, 2018. For the best experience, the Windows Server team recommends a clean install.

There are some known issues in this release.

Known issues with Windows Server build 17046

  • [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
  • Although installation will continue successfully, the product key will not activate.
