Though it was released over a decade ago, the DirectX End-User Runtime June 2010 remains one of the most downloaded and essential utilities for PC gamers, specifically those interested in retro gaming or preserving older software. While modern versions of DirectX (11, 12, and 12 Ultimate) are handled automatically via Windows Updates, the June 2010 package serves a specific, enduring purpose.
If you are building a new PC or reinstalling Windows, this runtime is the first thing you should download after your GPU drivers if you intend to play any game released prior to 2012. Steam (the gaming platform) is smart enough to automatically install these redistributables when you download an older game, but standalone installs, GOG installers, or physical disc installs will almost certainly require the June 2010 runtime. directx end user runtime june 2010
