Redlock

Redlock is a tool developed by lucasm and gus33000, two BetaWiki members and software developers. The initial version was released on 29 January 2020. The tool is designed to replicate Microsoft's original Redpill implementation as closely as possible. It is being actively developed. It is a C# wrapper around a C++ unencrypted reimplementation of shsxs.dll (as the original implementation was approximately 85 per cent encrypted), which is contained within the executable compressed with GZip.

While the practice of disabling the Software Protection Service is still present, there is a variety of improvements. One of them is the creation of a dynamically tailored shsxs.dll, making the tool's compatibility scope much wider. Product policies, system certificates, manifests and registry keys are applied dynamically as well. DISM is used to install the Immersive Browser. To demonstrate the accent capabilities of various early builds, it includes a copy of the Windows Developer Preview accent modified in order to be colorizable on builds that support it. Redlock is notable for being the first Redpill tool to include support for build 7850.

Compared to the previous third party tools, Redlock has become the preferred tool for unlocking Metro due to its compact size, speed, and cleaner method of enabling the features.
