It is a well-known internet meme that "WinRAR never expires." This is partially true. WinRAR functions on a "shareware" model. When you download it, you get a 40-day trial. However, once the 40 days are up, the software does not stop working.

This leads many users to search for a cracked rarreg.key file online. Winrar Key Rarreg.key 64 Bit
