powershell - 通过 PowerShell 在 Windows 10 中更改和更新光标的大小

问题描述

我编写了下面的代码来影响（我认为）是负责 Windows 10 中光标和指针大小的唯一 reg 键。

这是我到目前为止的代码（里面有一些额外的评论）：

$RegConnect             = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]"CurrentUser", "$env:COMPUTERNAME")
$RegCursorsAccess       = $RegConnect.OpenSubKey("Software\Microsoft\Accessibility", $true)
$RegCursorsControlPanel = $RegConnect.OpenSubKey("Control Panel\Cursors", $true)

# In the code below I'm trying to change the size of the cursor.

$RegCursorsControlPanel.SetValue("CursorBaseSize", 48)
$RegCursorsAccess.SetValue("CursorSize", 3)

$RegCursorsAccess.Close()
$RegConnect.Close()

# This section is where I thought it would update the cursor size.

# Here is where it lists stuff relating to setting and updating any settings changed.
# https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-systemparametersinfoa
    # SPI_SETCURSORS
    # 0x0057
    # Reloads the system cursors. Set the uiParam parameter to zero and the pvParam parameter to NULL.

$CSharpSig = @'
[DllImport("user32.dll", EntryPoint = "SystemParametersInfo")]
public static extern bool SystemParametersInfo(
                  uint uiAction,
                  uint uiParam,
                  uint pvParam,
                  uint fWinIni);
'@
$CursorRefresh = Add-Type -MemberDefinition $CSharpSig -Name WinAPICall -Namespace SystemParamInfo -PassThru
$CursorRefresh::SystemParametersInfo(0x0057,0,$null,0)

它将更改注册表中的正确值。

因此，如果我运行此 PowerShell 代码，则易于访问设置中的鼠标大小处于正确值。
