geez they couldn't have chosen location that is more inappropriate than that
It's the required spot for Vista certification I think. And it does make a good amount of sense. Programs are in Programs, user data is stored in the Documents and settings. And in all users so everyone in Vista can access all the data (skins). You can move it if you want to change the registry
The location where WB looks for skins is set by two registry keys. They must be set to the same directory.
HKEY_CURRENT_USER\Software\Stardock\WindowBlinds\wb5.ini\Installed\Path
and
HKEY_LOCAL_MACHINE\Software\Stardock\WindowBlinds\wb5.ini\Installed\Path
If
you want to put your skins elsewhere then you can change those keys and
copy ALL of the directories off the current WB skin directory to that
directory.
