Is K-Lite codec pack safe to install?

Windows Media Player won't play some of my older video files and people keep recommending K-Lite. Last time I installed a codec pack it came with junk toolbars. Is it safe these days and what should I untick during setup?

The pack itself is fine and has been around forever. The risk is where you get it from: random download sites wrap it in their own installer full of adware. Get it from the official codecguide site only, and read each installer screen, untick any extra offers. Honestly though, most people don't need it any more. VLC plays almost anything on its own without touching your system codecs, so try that first and only install K-Lite if a specific program still can't open your files.
