Deletes the Explorer thumbnail cache (thumbcache_*.db). Fixes wrong/blank thumbnails and frees space; Explorer rebuilds them on demand. Restarts Explorer so the locked cache files can be removed.
MaxTweaks applies this tweak with one click and clearly marks it as a one-shot action so you always know what can and can’t be undone. A System Restore point is offered before batch changes, and every tweak links to its official source.
