适配Win7/8/10：Java Swing全屏程序无需重启禁用组合键等的PowerShell命令

Alright, let's break down how to handle each of your requirements with PowerShell commands that work without a system restart, and are compatible with Windows 7, 8, and 10. Most of these require running PowerShell (and your Java app) as Administrator to take full effect, so keep that in mind.

1. Disable Alt+Tab and Alt+Space Shortcuts #

These are system-level or window-specific shortcuts, so we'll cover both global and app-targeted approaches.

Disabling Alt+Tab Globally #

This modifies the Windows registry to block Alt+Tab entirely, and only requires restarting Explorer (not the whole system) to apply:

# Disable Alt+Tab
Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" -Name "DisableAltTab" -Value 1 -Type DWord

# Refresh Explorer to apply changes immediately
Stop-Process -Name explorer -Force; Start-Process explorer

Disabling Alt+Space (Window System Menu) #

Instead of blocking this globally (which would affect all apps), it's better to target your Swing JFrame specifically. This uses Windows API calls via PowerShell to remove the system menu from your app's window:

# First, get the handle of your Swing app's window (replace with your app's actual window title)
$appWindowHandle = (Get-Process | Where-Object {$_.MainWindowTitle -eq "Your Swing App Title"}).MainWindowHandle

# Import Win32 APIs to modify the window menu
Add-Type @"
using System;
using System.Runtime.InteropServices;
public class Win32Utils {
    [DllImport("user32.dll")]
    public static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert);
    [DllImport("user32.dll")]
    public static extern bool RemoveMenu(IntPtr hMenu, uint uPosition, uint uFlags);
}
"@

# Remove the system menu (blocks Alt+Space for your app only)
$systemMenu = [Win32Utils]::GetSystemMenu($appWindowHandle, $false)
[Win32Utils]::RemoveMenu($systemMenu, 0xFFFFFFFF, 0x00000001)

This change only affects your app's window—once the window closes, the system menu functionality returns to normal for other apps.

2. Disable Third-Party App Notifications (e.g., Outlook) #

We can target either global notifications or specific apps like Outlook, depending on your needs.

Global Notification Disable #

• Windows 10: Blocks toast notifications

Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\PushNotifications" -Name "ToastEnabled" -Value 0 -Type DWord

• Windows 7/8: Disables balloon-style notifications

Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" -Name "EnableBalloonTips" -Value 0 -Type DWord

Run this to apply changes immediately:

Stop-Process -Name explorer -Force; Start-Process explorer

Disable Outlook Notifications Specifically (Windows 10) #

If you don't want to block all notifications, target Outlook directly:

# Find Outlook's unique app ID in the registry
$outlookAppId = (Get-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Notifications\Settings\*" | 
    Where-Object {$_.DisplayName -eq "Microsoft Outlook"}).PSChildName

# Disable notifications for Outlook
Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Notifications\Settings\$outlookAppId" -Name "Enabled" -Value 0 -Type DWord

This takes effect right away without needing to restart Explorer.

Critical: Reverting Changes #

Don't forget to restore these settings when your Swing app closes—otherwise, users will be stuck with disabled shortcuts/notifications. Here are the revert commands:

Revert Alt+Tab #

Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" -Name "DisableAltTab" -Value 0 -Type DWord
Stop-Process -Name explorer -Force; Start-Process explorer

Revert Notifications #

• Windows 10:

Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\PushNotifications" -Name "ToastEnabled" -Value 1 -Type DWord
Stop-Process -Name explorer -Force; Start-Process explorer

• Windows 7/8:

Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" -Name "EnableBalloonTips" -Value 1 -Type DWord
Stop-Process -Name explorer -Force; Start-Process explorer

Calling PowerShell from Java Swing #

To execute these commands directly from your JFrame app, use Runtime.exec() (make sure your app runs as Administrator):

// Example: Disable Alt+Tab from Java
try {
    String command = "powershell.exe -Command \"Set-ItemProperty -Path 'HKCU:\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced' -Name 'DisableAltTab' -Value 1 -Type DWord; Stop-Process -Name explorer -Force; Start-Process explorer\"";
    Runtime.getRuntime().exec(command);
} catch (Exception e) {
    e.printStackTrace();
}
