Back in the day, I was deep into Windows Mobile development—specifically trying to create CAB files that would perform registry edits on Pocket PCs. I remember scouring the net for a dummy-friendly guide to .NET (Compact Framework) for exactly that purpose. It felt like a niche corner of mobile dev, but it was fascinating how much control you had over the device.
Fast forward to 2026, and mobile development has changed beyond recognition. Windows Mobile is all but gone, and we’re now building apps using .NET MAUI, Xamarin, or native SDKs for Android and iOS. But I still find myself missing the simplicity of CAB files and direct registry access. Of course, today we have APIs and preferences frameworks, but there was something satisfying about crafting a custom CAB.
Does anyone else remember working with Windows Mobile? How did you handle registry edits back then? And for those who are curious, what would be the modern equivalent of that workflow? I’m thinking of trying to emulate it for fun, maybe using a modern .NET framework targeting Android or iOS settings storage.
If you have any old guides, blog posts, or just memories of that era, share them here. I’d love to see if anyone preserved those resources or documented the process elsewhere. Also, if you’re new to mobile development, it’s worth understanding how far we’ve come—from cab files to app stores.

Topic Overview (Wikipedia):
Windows Mobile is a discontinued mobile operating system developed by Microsoft for smartphones and personal digital assistants (PDA). Designed to be the portable equivalent of the Windows desktop OS in the emerging mobile/portable area, the operating system is built on top of Windows CE and was originally released as Pocket PC 2000.

Reading through this thread takes me back. The CAB file approach for registry edits on Windows Mobile was indeed a unique blend of power and simplicity. Back then, we had direct access to the underlying system, which made tasks like tweaking settings or adding custom configurations straightforward through INF files and .NET Compact Framework code. The trade-off was the lack of sandboxing and security, but that was the charm of the era.
Today, with .NET MAUI and modern mobile SDKs, we’ve moved entirely away from such low-level access. On Android, you’d use SharedPreferences or the Settings API; on iOS, UserDefaults and the Settings bundle. These are intentionally restrictive to protect the OS and user data. The Mermaid diagram captures this shift perfectly: the left side shows the direct path from code to registry, while the right side illustrates the modern pipeline where settings are managed through high-level APIs. There’s still a need to persist configuration, but the implementation is cleaner and safer.
For anyone nostalgic about that workflow, you could recreate the spirit by building a .NET MAUI app that manages a set of preferences and exports them as a configuration file, similar to how CAB files encapsulated registry changes. The underlying philosophy remains: separate the configuration from the application logic. But instead of registry keys, you’d use JSON files or platform-specific storage. It’s a fun exercise to see how concepts evolve while the core intent persists. I’ve actually experimented with porting an old Windows Mobile registry editor to MAUI, and it’s surprising how much of the logic translates—except the part where you have to respect modern security boundaries. Great discussion, and I hope more people share their memories of those early days.
