WindowsTimeSynchronizer

🇬🇧 English | 🇩🇪 Deutsch

A small Windows tool that forces a system clock resync. It starts the Windows Time service and triggers an immediate sync via w32tm.

On first run, the app automatically registers itself as a scheduled task that runs at every login (with a 30-second delay). No manual setup needed — just run it once.

Requirements

• Windows 10 or 11
• Administrator rights (the app elevates itself via UAC)

Installation

1. Download WindowsTimeSynchronizer.exe from the Releases page.
2. Place it somewhere permanent, e.g. C:\Tools\WindowsTimeSynchronizer.exe.
3. Run it once — done.

If SmartScreen warns you, right-click the .exe → Properties → tick Unblock → OK.

What happens on launch

1. The app requests admin rights (UAC prompt on manual start).
2. It registers (or updates) a scheduled task so it runs automatically at every login.
3. It starts the Windows Time service and forces a resync.
