Clear icon cache in windows 7/8/10

Problem:

I want to clear the Windows icon cache because a Windows shortcut is currently displaying an old, incorrect icon.

Solution:

• press [Windows Key]+R (to get the run dialog)
• in windows 7/8, run the command: ie4uinit.exe -ClearIconCache
• in windows 10, run the command: ie4uinit.exe -show

Additional notes:

This was verified to work in Windows 7 and Windows 10 without requiring a restart. Your mileage may vary.
