Lotus 1-2-3 combined spreadsheet, graphing, and database functions in a way that revolutionized business computing. While modern alternatives like Microsoft Excel have long superseded it, many organizations still possess historical financial models, macros, and data stored in native .WK1 , .WK3 , or .WK4 formats. Furthermore, some users prefer Lotus’s keyboard-driven interface. Consequently, the ability to run Lotus 1-2-3 on Windows 10 remains a relevant, albeit niche, concern.

The inability to run original software on modern OSes risks losing the ability to verify computational results from historical spreadsheets. Financial audits, engineering calculations, and scientific data from the 1980s–1990s may depend on specific quirks of Lotus’s floating-point implementation (e.g., different rounding behavior from Excel). Running original binary code in a controlled emulator is the only method that guarantees bit-exact reproducibility. Consequently, the ability to run Lotus 1-2-3 on
