If you find that the icons in Visual Studio 2017 are missing, a potential fix is to delete a specific folder that contains icon cache, and then restart Visual Studio 2017. Here's how to do it:
1. Close Visual Studio 2017 if it's currently running.
2. Navigate to the following folder path in File Explorer:
%LocalAppData%\Microsoft\VisualStudio\15.0_[UniqueID]\ImageLibrary\
Replace [UniqueID] with your unique user ID.
3. Delete the `ImageLibrary` folder.
4. Restart Visual Studio 2017.
Upon restarting, Visual Studio 2017 should regenerate the missing icons, restoring them in the interface.
