Windows Frotz is an interpreter that can play all the old Infocom text adventures. Infocom used a novel approach to write their games: they had a system that produced a data file for the adventure that was the same on every computer, and an interpreter for every computer that could run all the games (It was actually a bit more complicated than that, but that's the basic idea).
During the late 1980s and early 1990s many people worked to decode Infocom's format, producing several interpreters for the format (which is called Z-code, or the Z-Machine, with the Z coming from Zork, Infocom's first game). Windows Frotz is the latest in this line of interpreters. During the early 1990s, Graham Nelson took the next step by writing a compiler for the format, called Inform. The result is that the modern text adventure community have written several hundred games in this format that can be played with this interpreter.
For ratings and descriptions of games you can play, search for Z-code games at IFDB.
Download and install Visual Studio 2019 Community edition from https://visualstudio.microsoft.com/. In the installer, under "Workloads", make sure that "Desktop development with C++" is selected, and under "Individual components" that "C++ MFC for latest build tools (x86 & x64)" is selected.
To be able to build the CHM help file, download and install Microsoft's HTML Help Workshop. Note that this is a link to the version on the Internet Archive as the link to this on Microsoft's site does not work at the moment.
Install git. I use the version of git that is part of MSYS2, a Linux-like environment for Windows, but Git for Windows can be used from a Windows command prompt.
Open the environment that you are using git from, and switch to the root directory that the build environment will be created under (from here referred to as "\
