Tray & badge	About

1. Get the installer from the Releases page
   (e.g. Win11ExtraClock-x64-*version*-setup.exe).
2. Run the installer and follow the steps.
3. Optional: keep the icon always visible via
   Settings → Personalization → Taskbar → Other system tray icons → turn On for “Win11 Extra Clock”.

Requirements

• Windows 11 build 22000+ (21H2 or newer).
• x64 system.

The installer and executable are not code-signed yet. On first run, Windows SmartScreen may warn that the app is from an unknown publisher.

If that happens:

1. Click More info
2. Click Run anyway

We plan to sign future releases. Until then, you can verify the download by checking the attached SHA-256 checksum and by downloading only from this GitHub repository.

• Click the time/date area on the Windows taskbar (the built-in tray clock).
• The Windows calendar opens and Win11 Extra Clock appears alongside it (seconds + long date).
• Close it by clicking the time/date again or anywhere outside the flyout.

• Open the tray menu → Show Test
• This shows the clock flyout without the Windows calendar, so you can position it anywhere you want and preview it.
• The Custom move... become active only when the position is set to Custom and the Show Test is active.
• Close it by uncheck it from tray menu.

• Click the app’s tray icon to open the menu (About, Exit, Position…).
• When a new version is out, the tray icon shows a small red badge and the menu displays Update available (bold).
  Click it to open the latest release.

• Tray menu → Position → choose Top-Left / Top-Right / Bottom-Left / Bottom-Right / etc., or Custom to fine-tune offsets.

• The option Start with Windows is already checked in the installer, the app launches automatically on sign-in.
  You can toggle this later from the Start-up folder or by reinstalling and changing the option.

The app checks for updates on startup and then periodically (default every 2 hours).
It reads a plain-text version file: https://raw.githubusercontent.com/floatweb/win11-extra-clock/main/version.txt

• Uses ETag / 304 to avoid unnecessary traffic
• Optional fallback to GitHub Releases API
• No personal data is sent, only a simple HTTP GET

A small log is written to: %LOCALAPPDATA%\Win11ExtraClock\update.log

Language files live in languages/. Add a JSON file with your strings. Switching language applies at runtime.

• No telemetry.
• Network calls are only made to read the version text (and the GitHub releases endpoint if enabled).

Prereqs

• Windows 11
• Visual Studio 2022 (with “.NET Desktop Development”)
• .NET 8 SDK
