On X Windows I had a cool 'silent-alarm" reminder script that would change my root window (background) color to solid red, just for a few seconds a few moments before changing it back. Is there a way to do this for Windows XP?
I'm thinking some kind of scheduled task that uses cscript to set registry keys (HKEY_CURRENT_USER\Control Panel\Desktop
) . However my attempts don't seem to have any effect. What do I have to signal to read those registry entries and re-draw the desktop?
You might have to remove
HKCU\Control Panel\Desktop\TranscodedImageCache
