You can use WMI or other tools for this since there is no <code>Remove-Service</code> cmdlet until Powershell 6.0 (<a href="https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/remove-service?view=powershell-6&amp;viewFallbackFrom=powershell-5" rel="noreferrer" title="Remove-Service module documentation for PowerShell 6.0">See Remove-Service doc)</a>

For example:

<pre><code>$service = Get-WmiObject -Class Win32_Service -Filter "Name='servicename'"
$service.delete()
</code></pre>

Or with the <code>sc.exe</code> tool:

<pre><code>sc.exe delete ServiceName
</code></pre>

Finally, if you do have access to PowerShell 6.0:

<pre><code>Remove-Service -Name ServiceName
</code></pre>

the most reliable method that does not have many dependencies.

blocks|key|1005552|text|我使用了"-ErrorAction+SilentlyContinue“解决方案，但后来遇到了问题，它留下了一个ErrorRecord。因此，这里有另一个使用"Get-+Service“检查服务是否存在的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1005553|#+Determines+if+a+Service+exists+with+a+name+as+defined+in+$ServiceName.

[bool]+$thisServiceExists+=+ServiceExists+"A+Service+Name"
$thisServiceExists+|code-block|syntax|javascript|1005554|但是ravikanth有最好的解决方案，因为如果服务不存在，Get-WmiObject不会抛出错误。所以我决定使用：|1005555|Function+ServiceExists([string]+$ServiceName)+{

I used the "-ErrorAction SilentlyContinue" solution but then later ran into the problem that it leaves an ErrorRecord behind. So here's another solution to just checking if the Service exists using "Get-Service". 

<pre><code># Determines if a Service exists with a name as defined in $ServiceName.
# Returns a boolean $True or $False.
Function ServiceExists([string] $ServiceName) {
 [bool] $Return = $False
 # If you use just "Get-Service $ServiceName", it will return an error if 
 # the service didn't exist. Trick Get-Service to return an array of 
 # Services, but only if the name exactly matches the $ServiceName. 
 # This way you can test if the array is emply.
 if ( Get-Service "$ServiceName*" -Include $ServiceName ) {
 $Return = $True
 }
 Return $Return
}

[bool] $thisServiceExists = ServiceExists "A Service Name"
$thisServiceExists 
</code></pre>

But ravikanth has the best solution since the Get-WmiObject will not throw an error if the Service didn't exist. So I settled on using:

<pre><code>Function ServiceExists([string] $ServiceName) {
 [bool] $Return = $False
 if ( Get-WmiObject -Class Win32_Service -Filter "Name='$ServiceName'" ) {
 $Return = $True
 }
 Return $Return
}
</code></pre>

So to offer a more complete solution:

<pre><code># Deletes a Service with a name as defined in $ServiceName.
# Returns a boolean $True or $False. $True if the Service didn't exist or was 
# successfully deleted after execution.
Function DeleteService([string] $ServiceName) {
 [bool] $Return = $False
 $Service = Get-WmiObject -Class Win32_Service -Filter "Name='$ServiceName'" 
 if ( $Service ) {
 $Service.Delete()
 if ( -Not ( ServiceExists $ServiceName ) ) {
 $Return = $True
 }
 } else {
 $Return = $True
 }
 Return $Return
}
</code></pre>

I am currently writing a deployment script that installs a number of Windows services.

The services names are versioned, so I want to delete the prior Windows service version as part of the installs of the new service.

How can I best do this in PowerShell?

我目前正在编写一个部署脚本，用于安装许多Windows服务。服务名称是版本化的，因此我希望在安装新服务时删除以前的Windows服务版本。我怎样才能最好地在PowerShell中做到这一点？
