Building desktop software begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross‑platform frameworks, and the distribution method. A clearly outlined MVP and an initial prototype validate workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, stability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures reliable daily use, while an update system and crash reporting ease long-term maintenance.
