By default, PowerPoint 2013 starts slideshows in Presenter View when connected to dual monitors. For many, this is an unexpected and un-welcomed change that complicates things in multi-user situations.
When searching online, many sites list how to disable this as an end user, but when you utilize DeepFreeze or similar tools in a domain environment, this isn’t going to help if your profiles are built on-demand.
My work-around was to find the registry key responsible and change it on the fly via a simple batch file dropped into the All Users startup folder (C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup in Windows 7).
reg add HKCU\Software\Microsoft\Office\15.0\PowerPoint\Options /v UseMonMgr /t REG_DWORD /d 0 /f
Hope this helps others!
Tim, this is exactly what I’m looking for. I work for a large hospital and this has become problematic for us. Thanks for sharing.
