Cannot set Lock Screen Image - Microsoft Community

since the  recent major update w10 browse button disabled when go try , change lock screen image.  stuck on old image , want change clicking browse button nothing.  there setting somewhere else may have set preventing me changing picture?  @ top in yellow text says, "some settings managed organization", cause?  if how in change settings organization?

it sounds local gpo (group policy object) got set prevent changing of lock screen.

in windows 10, open start menu , type in gpedit.msc hit enter.

on left under computer configuration, go administrative templates - control panel - personalization

when click folder, should see on right there might policy set 'prevent changing lock screen , logon image' double-click , disable.

hope helps!
