Hello 룡관 현,
I can confirm this appears to be a User Interface (UI) layout bug in the new Windows Server 2025 Start Menu. The container for the Shutdown Event Tracker is not rendering at the correct size, causing the text and dropdown menu to be truncated, as you've shown. This is likely an issue Microsoft's engineering team will need to address in a future cumulative update, especially as it may be related to display scaling or specific language packs like Korean.
In the meantime, you do not have to use the buggy Start Menu option. You have two easy and immediate workarounds to shut down or restart the server properly:
Workaround 1: Use the Alt + F4 Shortcut (Recommended)
- Click on any empty space on your desktop or click the Taskbar.
Press the Alt + F4 keys on your keyboard.
This will open the classic "Shut Down Windows" dialog box, which is not truncated and will display the Shutdown Event Tracker options correctly.
Workaround 2: Use the Command Line
Open PowerShell or Command Prompt as an administrator.
To restart, type: shutdown /r /t 0
To shut down, type: shutdown /s /t 0
This will also trigger the full-screen Shutdown Event Tracker, allowing you to select your reason without any UI truncation.
As a quick troubleshooting step, you can also check your display scaling. Right-click the desktop, go to Display settings, and see if the Scale is set to 100%. If it is set higher (like 125% or 150%), that is the most likely cause of this layout bug, and setting it to 100% might temporarily fix the Start Menu view.
