Frequently Asked Questions

The data is taken from Microsoft's Default Winget Package Directory, you can find it here. The data source is refreshed automatically around twice a day, and the source code for this site can be found on GitHub here. (More Technical Details/Questions there too!) Note that the data comes from developer provided information, and may not be fully representative of ARM Support for that software.

Some applications use a runtime/interpreter, i.e. .NET, JVM (Java Virtual Machine), Node etc. As such, some developers may opt to list their application as Neutral, which means you have to install the runtime to run the app. Most runtimes have ARM/ARM64 support, which means the app will most likely run on ARM.

Prism is Microsoft's emulation layer to run x86 applications on the ARM platform, similar to Apple's Rosetta 2 for their M-Series chips. This tool does not scan applications for their performance / compatibility with Prism. As of now, any applications marked x86 only will be considered not compatible with Windows on ARM, results may vary if run on actual hardware with emulation.

The ARM Architecture broadly refers to a set of reduced instructions for computers to run. This Architecture was created by Arm Holdings, and they licence this for equipment manufacturers like QualComm, Apple, to make processors based on the architecture.

The ARM Achitecture has the advantage of having a reduced instruction set, which allows for higher performance and energy efficiency. They have traditionally been used in your Phones, TVs and small devices for that very reason. Recently, they have also been coming to larger devices like laptops, which have traditionally relied on the older x64 architecture.
