从命令行在Windows上静默设置屏幕保护程序？

Question

我知道如果你跑:

rundll32.exe desk.cpl,InstallScreenSaver toasters.scr

您可以将屏幕保护程序设置为,toasters.scr但它也会打开屏幕保护程序配置对话框.有没有办法在Windows上设置屏幕保护程序而无需通过运行命令打开任何对话框？

Answer 1

现代方式，使用 powershell

Set-ItemProperty -Path "HKCU:\Control Panel\Desktop" -Name ScreenSaveActive -Value 1
Set-ItemProperty -Path "HKCU:\Control Panel\Desktop" -Name ScreenSaveTimeOut -Value 60
Set-ItemProperty -Path "HKCU:\Control Panel\Desktop" -Name scrnsave.exe -Value "c:\windows\system32\mystify.scr"

您可以将这些放在ScrnInstaller.ps1使用以下命令执行的脚本中：

$ powershell -WindowStyle hidden -f "ScrnInstaller.ps1"

注意：这些参数被组策略参数取代（例如，强制为企业中的用户设置屏幕保护程序）。您有几种方法可以在此处强制执行。

具有用户/域/站点意识：组策略

使用 powershell 和组策略，您可以管理 您影响更改的组织单位/域/站点，并且它优先于用户设置。

在屏幕保护程序超时的情况下更改组策略：

Get-Command -Module GroupPolicy
New-GPO -Name "ScreenSaverTimeOut" -Comment "Sets the time to 900 seconds"
Set-GPRegistryValue -Name "ScreenSaverTimeOut" -Key "HKCU\Software\Policies\Microsoft\Windows\Control Panel\Desktop" -ValueName ScreenSaveTimeOut -Type DWord -Value 900
New-GPLink -Name "ScreenSaverTimeOut" -Target "ou=MyOU,dc=myenterprise,dc=com"
gpupdate /force /target:computer

为 myenterprise.com。对于 New-GPLink 参数：msdn 参考

然后您可以查看您的全科医生：

Get-GPO -Name "ScreenSaverTimeOut" | Get-GPOReport -ReportType HTML -Path $Home\report.html
Invoke-Item $Home\report.html

我找到了两种方法:

1)添加注册表,确保处于活动状态并且setTimeOut(仅限几分钟)

CMD

reg add "HKEY_CURRENT_USER\Control Panel\Desktop" /v SCRNSAVE.EXE /t REG_SZ /d C:\Windows\System32\Mystify.scr /f
reg add "HKEY_CURRENT_USER\Control Panel\Desktop" /v ScreenSaveActive /t REG_SZ /d 1 /f
reg add "HKEY_CURRENT_USER\Control Panel\Desktop" /v ScreenSaveTimeOut /t REG_SZ /d 60 /f

JAVA

setScreenSaver(true, 1, "C:\\Windows\\System32\\Mystify.scr");

/**
 * set screen saver active, timeout and scr, only works in Windows
 * @param isActive
 * @param timeOutMin only minutes
 * @param pathToScr path to scr
 * @throws IOException
 */
public static void setScreenSaver(boolean isActive, int timeOutMin, String pathToScr) throws IOException{
    String _isActive = isActive ? "1" : "0";
    //only works with minutes, min. 1 min
    String _timeOut = timeOutMin > 1 ? timeOutMin*60+"" : "60";
    Runtime.getRuntime().exec(new String[] { "reg", "add", "HKEY_CURRENT_USER\\Control Panel\\Desktop", "/v", "SCRNSAVE.EXE", "/t", "REG_SZ", "/d", pathToScr,"/f" });
    Runtime.getRuntime().exec(new String[] { "reg", "add", "HKEY_CURRENT_USER\\Control Panel\\Desktop", "/v", "ScreenSaveActive", "/t", "REG_SZ", "/d", _isActive,"/f" });
    Runtime.getRuntime().exec(new String[] { "reg", "add", "HKEY_CURRENT_USER\\Control Panel\\Desktop", "/v", "ScreenSaveTimeOut", "/t", "REG_SZ", "/d", _timeOut,"/f" });
}

2)从注册表获取路径并重写scr文件,但如果设置为null,则无法执行此操作.
