If and when I can conclusively identify the culprit, I'll post that info here.
Luckily, I have a 4-TB scratch disk available, so I can shut down and archive the VM prior to each individual update- this prevents having to go all the way back to 1709 and endure the multi-reboot Windows 1803 update process for each test. I'm now using the Windows diagnostic tools wushowhide.diagcab and wu10.diagcab to attempt to suppress specific individual updates, so that I can see which update is responsible. The initial update from 1709 to 1803 still seems to allow the VM to work properly, but one of the many post-1803 bugfix updates that get installed immediately after the big feature update seems to be causing this. I am running Parallels 15, and this appears to have begun after my W10 VM took the "major feature update" to Windows 10 Version 1803. Once a fix is available, it will be included the next Parallels Desktop update and shipped to all Parallels Desktop editions, including the Standard Edition.I have been experiencing this post-login black screen for a number of days as well.

In the thread Parallels Support replies:Įnabling nested virtualization helps in updating to latest Windows Insider build which is only available with Pro and Business subscription. But then there were more details in the Parallels forum when a user complained that the Windows 10 Preview Build 20175.1000 under Parallels failed with the installation error 0xc1900101. While we do not have ETA for the fix, it has been prioritized appropriately and you can track the changes in the product at the corresponding knowledge base article page. We have escalated the issue you reported to the Development Team and they are working to address it in one of the future builds of Parallels Desktop for Mac. Subsequently, PKCano received a reply from Parallels as a mail: During a remote session with a Parallels engineer, he told the user to contact Microsoft. Therefore he opened a support ticket at Parallels. The Insider Preview builds of Windows 10 still could not be installed. Parallels recently released version 16, and PKCano hoped this would solve the problem. This is a common problem with virtualization software, usually it is removed at some point by updating the virtualization software. Starting with Windows 10 Pro Insider Build 20175.1000, these builds suddenly stopped installing.
