Windows 7/8 Wallpaper Registry Keys (Slideshow) [closed]

Question

I'm wondering where the registry keys are for the wallpaper locations, slideshow duration, and wallpaper fit so I can make a quick registry patch.

Answer 1

There is a registry entry which contains (but not controls) the current slideshow duration in miliseconds. It is

HKEY_CURRENT_USER\Control Panel\Personalization\Desktop Slideshow\Interval

You can change it, but the next time you use the theme, the duration will be 15 minutes again. That duration is copied from:

%USERPROFILE%\AppData\Local\Microsoft\Windows\<i>Themes\theme_name\theme_name.theme</i>  

(a text file) where there is an item named Interval near the end of the file. You can change the value of that entry to, say:

Interval=14400000

which is 4 hours, or any other value. But I do not know where the 15 minutes duration comes initially from.
