Redlock

Redlock is a tool developed by BetaWiki members and software developers lucasm and gus33000. The initial version was released on 29 January 2020. Its main goal is to replicate Microsoft's original Redpill implementation as closely as possible. It is in active development. The installer is written in C#.

While the practice of disabling the Software Protection Service is still present, it differs in a multitude of areas. To keep the footprint minimal, the tool ships with only one shsxs.dll per architecture. The DLL's contents as well as registry and file tweaks performed upon installation are tailored on the fly, greatly improving compatibility. DISM is used to install the Immersive Browser. Unlike other unlock tools, Redlock's shsxs.dll has been built from scratch and is available as an open source project. Prior to this tool's release, it was common to borrow the one found in Windows Developer Preview.

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, broader compatibility, and cleaner method of enabling the features.

Blue Screen of Death
Uninstalling Redlock in builds newer than Windows 8 build 8118 will cause a BSOD with  code.
