Q: "Unspecified error" When Adding a Link to Favorites in Windows Vista
A: Download fix_fav_il.vbs, save to Desktop and run the file. When you see the User Account Control elevation prompt, click Continue. The script opens an elevated Command Prompt window and fixes the integrity level setting automatically.
If everything is done well, you will see the
processed file: favorites
Successfully processed 1 files; Failed processing 0 files
Close the Command Prompt window.
