Bugs[edit | edit source]

Dynamic disks will fail I/O with a STATUS_INVALID_DEVICE_REQUEST error. This results in failures to mount or format the volume.
You can't upgrade from an older build to this one, a clean install is required.
The Health Attestation CSP fails with error code 500 when attempting to get a certificate.
If scatter-gather list (SGL) functionality is enabled, data corruption my occur on NVMe (NVM Express) drives.
The BFE (base filtering engine) service may fail to start, which prevents the Windows Defender firewall service (MpsSvc) from running.
There's a chance of a BSOD because of a kernel security check failure from a corrupted list entry in a deferred free pool.
On this build, Hyper-V isolated containers will fail to start with an error of "The description string for parameter reference (%1) could not be found. (0x3ab6)". To get around this bug, disable cloning optimization by executing the command reg ADD “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Containers” /v TemplateVmCount /t REG_DWORD /d 0. After that, either reboot or restart the vmcompute sevice.
Product keys refuse to activate on this build.
