We manage Windows systems for several clients and have seen an intermittent issue affecting user workstations after updates. The logon screen works normally, but after the user signs in, Windows displays a black screen while the mouse cursor remains visible and usable. We have not identified one specific update or hardware configuration that consistently triggers it, and servers and remote desktop sessions do not appear to be affected. Reinstalling graphics drivers helped temporarily in some cases, but the more reliable recovery method has been to open Task Manager with Ctrl+Shift+Esc, launch an elevated Command Prompt, run `powercfg /h off`, and reboot. This disables Windows Fast Startup, which may be involved. Has anyone encountered a similar problem, identified the underlying cause, or found a way to prevent it while maintaining normal update compliance?

I would prevent Windows Update from installing display drivers automatically and deploy graphics drivers through the device manufacturer instead. Also check firmware and chipset updates. Microsoft-supplied display drivers can occasionally cause problems, and testing the update with those driver updates excluded may help narrow down the cause.
The symptoms do not necessarily point to a graphics driver. If Task Manager opens and the cursor renders, Windows itself may be running while Explorer or another shell-related component is stuck. In some cases, restarting State Repository Service or WSAIFabric, then restarting Explorer, can bring the desktop back. There does not seem to be a universal fix, though.
There are several possible causes besides the update itself: antivirus or application-control software blocking Explorer, inaccessible mapped drives or DFS paths, printer-driver policies waiting for a timeout, disconnected printers, or older network-name dependencies. Since the problem is sporadic across different hardware, collect the update history, event logs, service status, and device-driver versions from affected machines rather than assuming it is purely a display issue.
That makes sense. We initially focused on video drivers because of the black screen, but the variety of affected systems suggests we need to compare services, security software, mapped resources, and update history across incidents.
We already reinstall graphics drivers when this happens, but that stopped being a dependable solution after a while. We will separate driver updates from the regular Windows update process and investigate firmware as well.
