How to Customize / Tweak Windows Vista ScreenSavers using Registry?

As we all know Microsoft shipped Windows Vista with a few new cool Screen savers which are:

Aurora
Bubbles
Mystify
Ribbons

Although these screen savers are cool but the worst thing is we are not allowed to change their settings. There is no Options box to change the settings.
Actually the screen savers were initially developed to be customizable but the Options window was disabled while releasing them for no reason?
If you open the screen savers MUI files in Resource Hacker or Resource Tuner, then you'll find their Options dialog boxes.
But you can use registry to make changes in these screen saver settings. Here I'll tell you about the registry locations and all customizable options for these screen savers:
Aurora:
1. Open regedit and goto:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Screensavers\Aurora

2. In right-side pane, create following DWORD values given in BOLD and set their values as mentioned below them:

Min Value - 1000000000

Max Value - 15
Speed
Min Value - 1000000000

AllScreensSame
This DOWRD value is used for multiple monitors. If you set it to 1, then all monitors will use the same configuration file and will show same screen saver otherwise not.
SpanMultiMon
This DWORD value is used for multiple monitors. If you set it to 1, then screen saver will move between both monitors otherwise it'll show on both screens separately.

NOTE: You can play with the above mentioned options by settings their values to anything falling under their limits. There are a few other unknown options available but I have not mentioned them cause we don't know their use.
If you want to revert back to default settings, then simply delete the newly created DWORD values.
