问题
I am not able to find the correct property/method to disable the auto recover option for powerpoint. For Excel and word its as below
For excel this will do it $wb.EnableAutoRecover = $False
and for word $word.Options.SaveInterval = 0
Any idea what I need to do for powerpoint? There is an 'Option's read only property.
回答1:
Most of PowerPoint's Options settings are stored in the registry, usually:
HKCU\Software\Microsoft\Office\xx.0\PowerPoint\Options
You can leave this open in Regedit, change an option in PPT then refresh Regedit to see what's changed.
In this case check:
FrequencyToSaveAutoRecoveryInfo
PowerPoint reads the options settings at startup, writes them out as the user makes changes and again at shutdown but never reads them from the registry again during a session. In other words, if you change the settings while PPT is running:
1) It'll have no effect, and 2) PowerPoint will overwrite your changes when it quits
You need to make any necessary changes while PPT is shut down.
