This issue is fixed in the Windows 10 1803 versions and newer.
I received a lot of positive feedback on my previous post on accessing the clipboard from the lock screen using the wireless password field.
Just out of curiosity I tried other combinations on doing the same thing, and I found out another cool trick to do the same using the Narrator feature in Windows.
You heard me (#LOL – Narrator is the component that reads stuff out loud) I did the same with Narrator. So, you are probably wondering how I did it using the Narrator. It is shown in the following video:
I also tried to «fuzz» the different fields to see if it is possible to break out of the Narrator application. I was not able to find any method.
Well, hope you enjoyed it and I hope Microsoft does something about this in the future. A quick fix to disable the narrator is to change the ACL on the Narrator.exe and deny read and execute to everyone. I have not found a Group Policy settings that disables this yet. I will update this post if I do.
Hope you enjoyed this post and find this exciting as I do. (I am such a geek)
A good point from Papagon in the comments. You can also change the content of the clipboard using CTRL+C.
