If you don't want to use PowerPoint (PPT) Viewer or creating a PPShow, try
this:
I find it easy when I am teaching with numerous PPT slides to create
shortcuts to the files by first creating a shortcut to the PPT program and
then including a switch and the PPT file name. You need to create the
shortcut from Windows Explorer program, drill down to C:\Program
Files\Microsoft Office and continue down the path until you find the
PowerPnt.exe file. Right click on it and the Create Shortcut. Drag the
shortcut to the desktop so you can edit it. (The reason you need to go this
way to create the shortcut is that MS prevents the easy copying of their
installation created shortcut for the Office.programs.)
Once you have the shortcut on the desktop modify it by right clicking it and
the click Properties. In the Target window under the Shortcut tab, tap your
End key. This will clear any selection of the text (you need all of it).
Then press the space bar one time and type /s (a forward slash and then the
s key) then space again. Type or copy the path and file name for the PPT
file you want to start full screen. When you double click the shortcut PPT
will start and load the file and start it in Show mode. (Pressing the Esc
key during the show will dump you out of PPT. Doing it this way will prevent
you from escaping out of the show and editing the file then reentering the
show like you can if you start the file normally, just be forewarned.)
Hope this helps, let us know
