The Windows Insider Program was also introduced with Windows 10, which boosted the company's engagement with beta testers as well as distributed new pre-release builds more frequently than the prior beta testing initiatives. This also greatly cut down the number of leaks from within the company, which in the past bothered the company due to legal complications of contracted features becoming available earlier than anticipated. However, while early Insider builds often contained some clearly unfinished features and did not attempt to hide them, the Windows team has gradually moved towards locking such features down using systems such as Velocity and only unlocking them in an almost finished state.
