Thumbnail and Icon Cache Rebuilder for Windows 10 is a portable freeware that will purge, clear, and delete your Thumbnail and Icon Cache in a click.

If your icons appear blank or look corrupted or do not refresh correctly, when they should, then it is quite possible that your icon cache database may have become corrupted on your Windows 10 PC. The same thing applies to Thumbnails too. If they do not display correctly then they may have become corrupted. In such a scenario, you may need to delete the cache files in order to rebuild the Icon cache and clear the Thumbnail cache. We have already seen how to rebuild Icon cache in Windows manually – but if-if you prefer to automate the process, use our Icon cache Rebuilder 2 for Windows 10.
