In Windows 10, version 1709, we introduced Dynamic Lock, including an inbox method using Bluetooth to detect whether a user is present and lock or unlock the PC. Because of this, and because third party partners didn't adopt the CDF method, we're no longer developing CDF Dynamic Lock APIs. 1809

You can launch Snip & Sketch directly and start a snip from there, or just press WIN + Shift + S. Snip & Sketch can also be launched from the “Screen snip” button in the Action Center. We're no longer developing the Snipping Tool as a separate app but are instead consolidating its functionality into Snip & Sketch. 1809
