Problem: Icons still wrong after refresh.
Solution: Ensure all iconcache files were deleted while Explorer was closed, then restart Explorer; sign out/in if needed.
Problem: Cache file "in use".
Solution: End the explorer.exe process first, then delete the cache files.
Problem: Thumbnails wrong, not icons.
Solution: Clear the Thumbnails via Disk Cleanup instead.
Problem: Desktop went blank.
Solution: That’s Explorer being closed — run explorer.exe from Task Manager > Run new task.
Conclusion
Rebuilding the icon cache fixes blank or incorrect icons without a reboot: close Explorer, delete the IconCache/iconcache files, and restart Explorer. Clear the Thumbnails via Disk Cleanup too if picture previews are affected.
