You can add / remove the Show setting by going to
Windows Explorer>Tools > Folder options > File Type > > PPT/PPTX>Advanced
To Add choose "NEW"
Action :
= S&how
Appication used :
"C:\Program Files\Microsoft Office\Office12\POWERPNT.EXE" /s "%1"
Alter the path/version if it's different
If you look at the S&how settings for a pps file you can copy the
"application used" setting and paste it in to the ppt settings
Hope that makes sense
