Building desktop software begins by selecting an appropriate platform approach: native options (Windows/macOS/Linux), cross-platform frameworks, and the deployment method. A clearly outlined MVP and an initial prototype help verify workflows, performance requirements, and the overall user experience on actual devices.

As the product evolves, reliability, updates, and packaging become essential. Thoughtful management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures daily usability, while an update system and crash reporting ease ongoing maintenance.
