Reviving PowerToys as Open-Source Software

From Legacy to Windows Feature Sandbox: Reviving PowerToys as Open-Source Software

Numerous tests missing or failing on Windows

Poor Test Coverage

Tests on ARM64 builds failed due to missing or under-optimized performance libraries

ARM64 Test Failures

Lack of support for key profiling and sparse computation

Feature Gaps (Kineto and MKL Sparse)

Modern C++ module adoption triggered build breaks and fragile integration points in Windows toolchains

C++20 Module Compilation Failures (MSVC)

Drove Windows open issues from 187 down to 91, essentially matching other platforms at 92

Issue Reduction to Near Parity

Enabled fine-grained performance profiling on Windows via Kineto (with CUPTI) for iterative optimization

Enhanced Observability & Diagnostics

Reduced build fragility and future-proofed the codebase through stable C++20 module integration across PyTorch’s public APIs

Modern C++ Adoption Without Friction

Re-enabled and stabilized MKL Sparse on Windows, giving developers reliable sparse tensor operations without workarounds

Sparse Compute Restored

Restored passing tests and enabled high-performance builds on Windows ARM64

Optimized ARM64 Performance

Janea Systems partnered with PyTorch to cut Windows-specific issues by 50%, enabling cross-platform parity and improved developer experience.
