使用注册表编辑器^{(Registry Editor)}可以轻松修改注册表^(Registry)项。但是，如果您的工作涉及大量脚本，并且您需要使用PowerShell修改注册表，那么本文应该对您有所帮助。

使用 PowerShell^{(Use PowerShell)}更改注册表^(Registry)值

在本文中，我们将了解如何使用两个著名的PowerShell cmdlet^{(PowerShell cmdlets)}修改注册表。第一个 cmdlet 是New-Item而第二个是Set-ItemProperty。您可以使用这些 cmdlet 中的任何一个来修改现有的注册表项或添加新的注册表值。

1]使用New-Item PowerShell cmdlet修改^(Modify)注册表

在此示例中，我将在以下位置创建AllowIndexingEncryptedStoresOrItems注册表DWORD

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Windows Search and set it to 1.

通常，创建此注册表DWORD是为了允许Windows 10^{(Windows 10)}索引加密文件。默认情况下，Windows Search注册表项不存在。所以我将首先创建它，然后我将创建注册表DWORD并将其设置为 1。您可以根据您的情况替换注册表项的位置和值。以下是涉及的步骤。

以管理员^{(Administrator)}身份打开Windows PowerShell。

键入以下内容并按 Enter 键转到注册表位置：

Set-Location -Path 'HKLM:\Software\Policies\Microsoft\Windows'

然后执行以下 cmdlet 以创建名为Windows Search^{(Windows Search)}的新注册表子项。如果注册表项已经存在，我在这里使用 -Force 参数来覆盖。

Get-Item -Path 'HKLM:\Software\Policies\Microsoft\Windows' | New-Item -Name 'Windows Search' -Force

现在创建注册表子键后，我现在将创建注册表DWORD并为此执行以下代码： 

New-ItemProperty -Path 'HKLM:\Software\Policies\Microsoft\Windows\Windows Search' -Name 'AllowIndexingEncryptedStoresOrItems' -Value "1" -PropertyType DWORD -Force

注意：^(Note:)如果要创建字符串，则必须使用 -PropertyType 作为字符串。

您可以执行 pop-location 返回到正常的PowerShell，您可以在其中执行其他 cmdlet。

2]使用Set-ItemProperty PowerShell cmdlet修改^(Modify)注册表

对于此示例，我将设置HideSCAVolume注册表 DWORD 为

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies to 0.

将此DWORD设置为 0 会在任务栏中丢失音量图标时恢复它。以下是执行此操作的步骤：

打开 Windows PowerShell（管理员）。

然后只需复制粘贴此 cmdlet 即可执行注册表操作。当然，你需要自己修改注册表的位置和值，在下面的代码中：

Set-ItemProperty -Path HKCU:\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer -Name HideSCAVolume -Value 0 -Force

使用此方法，您无需执行 pop-location 即可返回正常的PowerShell，因为注册表更改直接在此处进行。

我相信本指南可以帮助您使用Windows Powershell修改注册表。

Use PowerShell to modify or change Registry values

A Registry entry can be easily modified using Registry Editor. However, in a case where your work involves a lot of scripting and you ever need to modify the registry using PowerShell, then this article should help you.

Use PowerShell to change Registry values

In this article, we’ll see how to modify the registry using two well-known PowerShell cmdlets. The first cmdlet is New-Item while the second is Set-ItemProperty. You can use either of these cmdlets to modify an existing registry key or add a new registry value.

1] Modify registry using New-Item PowerShell cmdlet

In this example, I’ll be creating AllowIndexingEncryptedStoresOrItems registry DWORD at

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Windows Search and set it to 1.

Usually, this registry DWORD is created to allow Windows 10 to index encrypted files. The Windows Search registry key doesn’t exist by default. So I’ll be creating that first, and then I’ll create the registry DWORD and set it to 1. You can replace the registry key location and values in your case. Here are the steps involved.

Open Windows PowerShell as an Administrator.

Type following and press Enter key to go to registry location:

Set-Location -Path 'HKLM:\Software\Policies\Microsoft\Windows'

Then execute the following cmdlet to create the new registry sub-key named Windows Search. I’m using -Force parameter here to override if the registry items exist already.

Get-Item -Path 'HKLM:\Software\Policies\Microsoft\Windows' | New-Item -Name 'Windows Search' -Force

Now as the registry sub-key is created, I’ll now create registry DWORD and execute the following code for this: 

New-ItemProperty -Path 'HKLM:\Software\Policies\Microsoft\Windows\Windows Search' -Name 'AllowIndexingEncryptedStoresOrItems' -Value "1" -PropertyType DWORD -Force

Note: If you’re creating string, you have to use the -PropertyType as a string.

You can execute pop-location to go back to normal PowerShell where you can execute other cmdlets.

2] Modify registry using Set-ItemProperty PowerShell cmdlet

For this example, I’ll be setting HideSCAVolume registry DWORD at

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies to 0.

Setting this DWORD to 0 restores the Volume icon if it is missing from the taskbar. Here are the steps for this:

Open Windows PowerShell (Admin).

Then simply copy-paste this cmdlet to perform registry manipulation. Of course, you need to modify the registry location and value with your own, in the below-mentioned code:

Set-ItemProperty -Path HKCU:\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer -Name HideSCAVolume -Value 0 -Force

With this method, you don’t need to execute pop-location to go back to normal PowerShell as the registry change is directly made here.

I trust this guide helps you modify the registry using Windows Powershell.
