Deselect any "Load at startup" options in any customization software, unload all programs and return to default windows theme including all icons (use to "Display Properties>Themes tab" and select Windows XP, click "Apply" to return to default theme).
Try uninstalling, reboot machine, and delete any WindowBlinds folder left in "C:\Program Files\Stardock\Object Desktop" folder (where "C" is the letter drive).
Then reinstall WindowBlinds (as long as you have not changed (hacked) any "explorer.exe" settings, and your downloading functions are normal, you should be okay).
Note - back up any skins you want saved from the "C:\Program Files\Stardock\Object Desktop\WindowBlinds" folder.
Good luck.
