StandbyAndTimer

A Windows desktop utility for reducing input latency and managing system memory — designed for gamers and power users.

v2.1.0 — Five user-visible features bundled under the new "batch fixes, don't ship per-commit" cadence:

• Global hotkeys — Ctrl+Alt+P manual purge, Ctrl+Alt+T timer toggle.
• Tray single-click toggles window visibility instead of always showing.
• Notification preferences — per-balloon toggles in Settings (purge / timer / game).
• Idle-only auto-purge — threshold purges wait until you've been idle, so gaming isn't interrupted.
• Single-instance signal — re-launching while the app is running silently surfaces the live window.

Memory card bottom strip refreshed to Total | Free | Purges with left / center / right symmetry. The original WinForms release is preserved as v1.0.0 on the winforms-archive branch.

Features

• Timer Resolution Lock — pins the system timer at 0.5 ms via NtSetTimerResolution for lower input latency
• Standby Memory Purge — manual and automatic cleanup of the Windows Standby memory list via NtSetSystemInformation
• Game Mode — sets High CPU priority and full affinity on user-configured game processes
• System Tray — runs in the background with optional launch at Windows startup
• Dark / Light themes with English & Turkish localization
• Built-in update checker against GitHub Releases (download & install from inside the app)

Installation

1. Go to Releases and download the latest StandbyAndTimer_Setup_X.Y.Z.exe
2. Run the installer (UAC will prompt — Administrator privileges required)
3. Launch from the Start Menu

Requirements: Windows 10 21H1+ or Windows 11, x64, Administrator privileges. No separate .NET runtime install needed — the installer ships a self-contained .NET 10 build.

Architecture

WPF (.NET 10) with MVVM. All Win32 P/Invoke calls are isolated in Services/Native/NativeMethods.cs. See ARCHITECTURE.md for the full design breakdown.

Build from source

# Build (Debug or Release)
dotnet build StandbyAndTimer/StandbyAndTimer.csproj -c Release

# Run (must be Administrator for the P/Invoke calls to succeed)
dotnet run --project StandbyAndTimer/StandbyAndTimer.csproj

To produce a redistributable installer (Inno Setup 6 required):

.\build-installer.ps1 -Version 2.1.0

Output: installer/dist/StandbyAndTimer_Setup_2.1.0.exe (~72 MB self-contained).

Install via winget

Once the package is published to the community repository:

winget install Layellie.StandbyAndTimer

The manifest lives at winget-manifests/ and is submitted to microsoft/winget-pkgs with each release.

Version history

Full per-release notes are on the Releases page. v2.0.8, v2.0.9, and v2.0.10 are rapid-iteration interim builds of the Settings-panel refresh and are marked pre-release on GitHub — install v2.0.11 instead.
