FairUse4WM 1.3

FairUse4WM is a software program that was developed by the programmer viodentia. Its main purpose is to remove digital rights management (DRM) restrictions from Windows Media Audio (WMA) and Windows Media Video (WMV) files. The program achieved this by utilizing a process known as "reverse engineering" which allowed users to make copies of WMA and WMV files without being restricted by the DRM technology.

The program was first released in 2006 and quickly gained popularity among those who were looking for a way to remove the restrictions on their media files. However, its use soon became controversial as music and movie companies claimed that it was being used to facilitate piracy. This led to a legal battle between viodentia and several companies, including Microsoft, who accused him of violating their intellectual property rights.

Despite the controversy surrounding its use, FairUse4WM remains a popular tool for those who want to remove DRM from their media files. However, it should be noted that using the software may violate copyright laws in some countries and could result in legal consequences.
