del /s /q /f /a:h Thumbs.db

There is a similar snippet on the site, yet it is listed for Windows Powershell, while the syntax is clearly Batch, and secondly, it is very incomplete and no response is coming from the author, so I'm posting my completer version here.

Beware, this will delete all Thumbs.db files that are hidden. If you want to delete the ones that aren't hidden too, you'll have to do it agin without the /a:h in there.

Remove all Thumbs.db files
