What's the problem?

HP computer users was plagued with a strange issue Windows 10 Creators Update (Version 1703). After installing updates from September 12, 2017, the screen went black for up to 10 minutes, after logging in to the user account.

Microsoft offers Update KB4043292

After HP provided a fix that deleted the competing registry values, Microsoft also offered Update KB4043292 (Black screen when Windows 10 restarts after a Windows update on some OEM factory-imaged devices). This update is intended to fix the following problem:

When restarting Windows 10 Version 1703 after a Windows Store application update is installed, some Windows 10 devices may experience a black screen for 5-10 minutes. This occurs because the devices have OEM factory images that were released with registry keys that conflict with the app readiness service.
