Let me first tell you how awesome this site has been over the last couple of days. I have been messing with my computer; had to format 4 times and learned allot
All the info I needed was right here, However now i'm kinda in a pickle.
I'm trying to remove the Arrow key from the logon screen.
My first guess would be its also in the Authui.dll, but thats a dangerous file to go messing about if your not sure ^^.
Now if anyone could tell me I would be ever so greatfull.
You are correct it is in the authui.dll in both C:\Windows\System32 and C:\Windows\SysWOW64 they are in a bitmap folder depending on your DPI setting they could be any of the following that I have highlighted below in the screenshot.
You will need a resource hacker of some kind to extract the images and edit them and then import them back in.
Yes with a resource hacker of some kind. Then a image editor to edit the images make them transparent, then import the images back in the authui.dll, Then you will need to take ownership, give yourself permission, rename the default authui.dll to authui.bak.dll and copy the authui.dll you edited back in place.
Hint: work on a copy of the authui.dll so you do not harm the default authui.dll

when i change pictures after pressing alt+ctrl+del or log off windows i see this error "Failure to open windows security and logon options"
and black screen and i cant logon to my computer
why this happening
This method has also not worked for me for removing the arrow.
I followed this method for changing the "Ease Of Access" icon on the lock screen, as I have set that button to take a screenshot rather, and that worked perfectly. But that was only one bmp image to replace (also in authui.dll).
I have replaced all the images of an arrow in authui.dll with transparent bmp's. I made sure to make them the same resolution and bit depth as the originals. When I press Win+L I just get a black screen with a mouse cursor and I can't do anything. Luckily I have Windows 10 dual booted so I was able to hard reboot into Win10 and copy the original file back.
Editing
Code:
C:\Windows\SysWOW64\authui.dll
seems to make no difference so I have just been focusing on
Code:
C:\Windows\System32\authui.dll
Not sure why it worked for the one picture but not the other one. Anyone know?
