It is not usual, but some files, when executed by the Windows Media Player, activate scripts that take you to certain web pages that open to you in popup windows, which is always a nuisance and a constant nuisance. To avoid this, WMPopKill has been created.
WMPopKill is a tool, totally free, that will deactivate, in your Windows Media Player, all those scripts. In this way, the annoying popups will never jump back from your player (or, worse, that one of these popups will start unauthorized downloads on your computer).
In addition, WMPopKill barely consumes system resources.
You can free download WMPopKill 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
