Application Architecture & Specifications
A comprehensive breakdown of the native Windows 11 subsystems, kernel APIs, and packaging architecture powering Uptime.
Application Architecture & Specifications
Subsystems & Core Implementations
Detailed view of internal subsystems designed for zero latency and privacy.
Kernel Event Synchronization
Utilizes native Win32 GetTickCount64 and OS power state event notifications without polling.
- • Nanosecond-precision timestamp computation
- • Zero thread wakeups during computer idle
- • Seamless resume from Modern Standby & S3/S4 sleep
Safe RAM Compaction
Invokes the native Win32 EmptyWorkingSet kernel API to release standby and cached pages to the system pool safely.
- • Zero risk of process crash or uncommitted data loss
- • Instantly frees hundreds of standby megabytes
- • Operates within standard user privilege space
DirectComposition & Acrylic
Built natively using Windows App SDK XAML and DirectComposition hardware pipelines for fluid 120Hz/144Hz high refresh rate rendering.
- • Native Acrylic translucent glass backdrop
- • Per-Monitor V2 high-DPI scaling intelligence
- • Freely draggable overlay with coordinate persistence
MSIX Sandbox Isolation
Declared with zero network capabilities (InternetClient omitted) guaranteeing that no telemetry can leave your machine.
- • 100% air-gapped system monitoring
- • Clean installation and uninstallation without residual registry bloat
- • Cryptographically signed certificate verification
