Hi, The problem is that windeploy isn't the fake boot screen you are referring to. Windeploy is the component that changes the text, such as, "Starting Services" and "Getting Devices Ready **%". But not all is lost, you can still access this mode, which people call "Windows 10 MS-DOS mode". In this mode, you will be running as system giving you full control over your system, which means you can cause a quite large around of damage, so just be careful, and of course, I can't be help responsible for any problems you cause :)
Before starting, create a restore point just in case anything happens
To Enter MS-DOS Mode:
-- On your system, open regedit.exe
-- go to "Computer\HKEY_LOCAL_MACHINE\SYSTEM\Setup"
-- Change "CmdLine" from "oobe\windeploy.exe" to cmd.exe
-- Change "SystemSetupInProgress" from "0" to "1"
-- Change "SetupType" from "0" to "1"
-- Then Restart your PC.
A Command Prompt should appear on startup, if not do "SHIFT+F10" to open one.
Please make sure you know what to change and don't change anything else
To Exit MS-DOS Mode:
-- Just change the values back to what they where before in regedit.exe
-- Then do "shutdown /r /t 0" to restart your PC after the value changes to get back to your desktop.
Hope this helps :)
