Major Bug in Windows 11 26120.1912 System Login Function

lornshrimpThere is official documentation on how to sideload apps, possibly even the app store itself, though that's not the most common thing people would do. When doing offline deployment / provisioning of Windows images, sideloading is a normal process. This other link is an official repo for Winget, which is used by the operating system to install applications and frameworks. I used Winget to do everything btw, which may seem surprising if you're not used to that:

lornshrimp Most people who experience this, are missing 5 apps that are installed by default. On the release channel build 26100.2033, this is also an issue.

NOTE: If Task Manager is running, you can use both the Command Prompt, and the file manager built into Notepad's open file dialog box, as a temporary replacement for Windows Explorer. When you reset the Start Menu or another app, and those dependencies / frameworks are paused, but not staged, meaning they're physically not present, you didn't reset them first, then of course it will glitch out. Depending on the situation, if you close userinit.exe and shellhost.exe, which will constantly restart, it will stop flashing long enough for you to use xcopy without getting interrupted too many times.

I mounted an RTM version of Win 11 24H2, with no patches, and copied them back over. Then I staged each one, by resetting them, before trying to reset the others. Btw even if you have to do this to activate Windows, they won't be fully functional UNLESS you have already activated your copy of Windows. So you will have to reset them, but you can't even fully utilize them until you activate. ( It will just give you access denied errors, meaning it will stay locked. This has little to do with AUMID or even the access control entries for that one set of files. What I mean, is that while that's important, it will only influence the outcome, once it's activated. ) This glitch appears when you go to reset an app without the dependencies / frameworks in place:

I have the same issue on one of my machines, but not on the other two oddly enough. I am on build 26100.2152.

Also to add, 

dsregcmd /status

just hangs.
