I would like to change the Windows 8 Lock Screen background image via c# code.
I am very familiar with how to do this in Windows 7, and also that Windows 8 doesn't support this method.
I tried using Process Monitor while changing it over and over again through SystemSettings.exe but nothing stood out to me.
This seems to be the only discussion that's gotten anywhere: http://social.technet.microsoft.com/Forums/en-US/W8ITProPreRel/thread/a8db890c-204f-404a-bf74-3aa4c895b183
Take a look to - Lock screen personalization sample (How to use
LockScreen API
to set the current user's lock screen image). Maybe would be useful for you.
