This appears to be the same issue being discussed and looked into by Dell engineering in this thread: [URL] The "black screen" issue is related to the App Readiness service. If you disable that service it fixes the black screen issue but then causes lots of issues with Windows 10 "Apps" and the Microsoft/Windows Store...so it appears this is just all one big issue with Dell's OEM Windows 10 image. Yes -- you can just install Windows 10 from Microsoft's Media Creation Tool without a key. It will pull the key from the BIOS and activate. We are doing this to all new Dell machines until Dell (hopefully) releases a fix. Or, maybe once they start shipping with 1803 it won't be an issue.
I work for a small business which only orders a handful of laptops (always Precision) a year, and always with OEM Windows 10 Pro licenses.   The last three Precision 7520's, which have been delivered over the last 6 weeks or so, have all exhibited the same symptoms with domain accounts using the Windows 10 Microsoft Store.  I'll outline my entire workflow below.   I've investigated the App Store issue in depth and I've tried numerous workarounds that I've encountered on various websites, such as: Unfortunately, none of these has been able to activate the Microsoft Store or any of its preinstalled apps for the affected domain user. Completely resetting the OS from within windows and then going through the entire process of building the user's profile worked one time, but did not work the second two times.  Either way, this is something that I'd like to avoid as it is a very time consuming process. After observing the same behavior when using Dell's preinstalled OS on the two newest systems, I simply reinstalled Windows 10 Professional from Microsoft's Windows 10 image (created from MediaCreationTool) on them, and everything has worked flawlessly as outlined below. With all of that in mind, it seems like there might be some issues with Dell's most recent Windows 10 image, or perhaps with my workflow.  Has anyone else observed similar behaviour?  If so, can you provide any additional insight as to what exactly is going wrong and how I might go about fixing it quickly?
