Windows 如何使用Powershell更改“我的电脑桌面”图标？

我正在尝试学习一点Shell脚本，因为测试自动化现在似乎越来越流行

我对Powershell的理解相当笼统。我当前的目标是更改我的电脑桌面图标

# Changes the My Computer desktop icon name from "This PC" to "VSDC0365".

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

$My_Computer = 17

$Shell = New-Object -COMObject Shell.Application

$NSComputer = $Shell.Namespace($My_Computer)

$NSComputer.Self.Name = $Env:COMPUTERNAME

在使用Powershell时，我还没有接触到Microsoft Windows 10操作系统的某些方面。我希望也许比我多产的作家能帮助我实现这个目标

我刚刚测试了两个代码片段，它们在第一次尝试时意外地成功运行

第一个可以称为

Create\u Shortcut.PS1

，它为可以运行批处理文件的命令行预处理系统创建一个桌面图标

# Creates the command-line desktop icon.

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

$TargetFile = "C:\Windows\System32\Cmd.Exe"

$ShortcutFile = "\\ISXPFV01.hd00.example.com\us_qv2_dem_user_data_pool_nra$\EE65037.HD00\Desktop\Command-Line.Lnk"

$WScriptShell = New-Object -COMObject WScript.Shell

$Shortcut = $WScriptShell.CreateShortcut($ShortcutFile)

$Shortcut.TargetPath = $TargetFile

$Shortcut.Save()

第二个可能被称为

Rename\u My\u Computer.PS1

，它重命名我的电脑桌面图标

# Changes the My Computer desktop icon name from "This PC" to "VSDC0365".

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

$My_Computer = 17

$Shell = New-Object -COMObject Shell.Application

$NSComputer = $Shell.Namespace($My_Computer)

$NSComputer.Self.Name = $Env:COMPUTERNAME

我感兴趣的东西对于比我更有经验的人来说可能非常简单。我需要通过指定路径来更改“我的电脑桌面”图标

由于我还没有达到这一目标，我们非常感谢在这个问题上提供的任何帮助

谢谢你的阅读

在@Theo的精彩评论后更新：

一个新的令人惊讶的工作片段，它成功地生成了“我的电脑桌面”图标：

# HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\HideDesktopIcons\NewStartPanel\
# {20D04FE0-3AEA-1069-A2D8-08002B30309D}
# 0 = show
# 1 = hide

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

$Path = "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\HideDesktopIcons\NewStartPanel"

$Name = "{20D04FE0-3AEA-1069-A2D8-08002B30309D}"

$Exist = "Get-ItemProperty -Path $Path -Name $Name"

if ($Exist)
{
    Set-ItemProperty -Path $Path -Name $Name -Value 0
}
Else
{
    New-ItemProperty -Path $Path -Name $Name -Value 0
}

现在，我所要做的就是在设置了他在评论中提到的设置之后，通过编程方式按F5刷新桌面视图

与刷新相关的另一个更新：

另一个令人惊讶的工作片段，刷新桌面视图：

# Refresh Desktop Ability

$Definition = @'

    [System.Runtime.InteropServices.DllImport("Shell32.dll")]

    private static extern int SHChangeNotify(int eventId, int flags, IntPtr item1, IntPtr item2);

    public static void Refresh() {
        SHChangeNotify(0x8000000, 0x1000, IntPtr.Zero, IntPtr.Zero);
    }
'@

Add-Type -MemberDefinition $Definition -Namespace WinAPI -Name Explorer

# Refresh desktop icons
[WinAPI.Explorer]::Refresh()

现在剩下的一切就是在刷新之前以某种方式更改我的电脑桌面图标

与取得该注册表项所有权相关的更新：

棘手的事情。我不知道事情会变得这么复杂

当前，它失败，错误消息以以下消息开头：

关于@Theo第二版重命名我的电脑桌面图标的更新：

这个版本还不适合我

它的测试非常简单：

• 我正在手动将我的电脑桌面图标重命名为

  fififi

• 然后我运行这个片段
• 然后手动刷新桌面视图

虽然我希望我的电脑桌面图标重新命名为

工作笔记本

，但它的名称仍然固定为

fififi

如评论所述，更改“计算机”图标标题相当麻烦

下面的代码适用于使用PowerShell 5.1的Windows 10 Pro

您需要以管理员身份运行此程序

在所有这些之后，桌面上还没有显示计算机名。您需要在桌面上按F5，或使用找到的代码刷新桌面

---

要更改图标本身，需要更改registrypath中的默认值

HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\DefaultIcon 

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\DefaultIcon

用于将来的新登录，或registrypath

HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\DefaultIcon 

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\DefaultIcon

对于当前用户

默认情况下，它指向

%SystemRoot%\System32\imageres.dll，-109

，这意味着它从imageres.dll中提取图标编号109。 在那个dll中。共有343个图标，因此您可以选择使用同一资源中的另一个图标，或从另一个现有dll中选择一个图标。（例如，您可以使用from nirsoft）

我还没有对此进行测试，但也可以让它指向您自己的图标的完整路径和文件名，如

%SystemDrive%\MyComputerIcon.ico

例如，这将更新图标以使用imageres.dll图标编号149

$regPath = 'Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\DefaultIcon'
Set-ItemProperty -Path $regPath -Name '(Default)' -Value '%SystemRoot%\System32\imageres.dll,-149' -Type ExpandString -Force

看起来像这样

---

您需要将

HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}

注册表项设置为类似于

%UserName%on%ComputerName%”的
属性。但是，只有首先获得该密钥的所有权，才能这样做。请记住，这个属性属于
ExpandString
（又称
REG\u EXPAND\u SZ
）你能看一看，@Theo，我在问题正文中附加的最新片段，告诉我它是否至少接近你在评论中写的内容吗？我不确定你是否意识到，但是
HKEY\U CLASSES\U ROOT
实际上不是一个合适的注册表根键。它实际上是一个映射键，包含来自其他根键的信息的串联。您需要的是其他根键之一，
HKEY\u LOCAL\u MACHINE\SOFTWARE\Classes
。因此，您可能会发现，用
HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}
替换
HKEY_CLASSES\u ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}
，如果不是更多的话，也是有成效的。对此我深表歉意
