A lightweight Windows diagnostic utility that inspects system build parameters, Velocity Feature IDs, and hardware configuration to determine if the K2 Low Latency Profile feature is available and active on your system.
Available as both a modern WPF GUI Desktop App (.NET 10) and a standalone PowerShell CLI Script.
- Dual Interface: Choose between the native WPF GUI desktop app or the classic PowerShell CLI script.
- Build & Revision Detection: Evaluates system build metrics and Universal Build Revision (UBR) to identify
rs_prereleaseorge_releasetargets accurately. - Velocity Feature ID Inspection: Scans registry override keys (
HKLM:\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides) for Velocity IDs60716524and61391826. - Hardware Telemetry: Displays CPU core/thread counts, total RAM capacity and speed, GPU model, and physical dedicated VRAM.
- Dormant & CFR Rollout Detection: Clearly distinguishes between unsupported builds, dormant staged code awaiting Microsoft cloud deployment, and active velocity states.
