I strongly recommend everyone try running Slimdrivers on this build. It found so many up to date drivers over the 2005/2006 era ones Windows 10 installed by default. Everything from audio and SD right up to graphics drivers.
Seriously, it has no single effect on the logon screen. I even delete them in some instant to see what happens and nothing. It is probably embedded in system file or something.
Did some checking, the log on screen might be here: C:\ProgramData\Microsoft\Windows\SystemData\S-1-5-21-214355377-2697743858-1179091297-1000\ReadOnly\LockScreen_A The System Data folder needs to have it's permissions changed to access it
I had capture the files from my Laptop and could upload to Mega. Compressed to .RAR it's app. 70MB. Just let me know you want!
I managed to open the folder and there was these weird lock screen images. But not the hero wallpaper
