您要做的第一件事是查看已启用的功能，为此，我们需要将Get-WindowsOptionalFeature cmdlet的输出传递到管道中，在此可以对其进行过滤和格式化：
Get-WindowsOptionalFeature –Online | Where-Object {$_.State –eq “Enabled”} | Format-Table
Get-WindowsOptionalFeature –在线| 哪里对象{$ _。State -eq“ Enabled”} | 格式表
That will give you a nice tabulated view of what is enabled.

如果要查看禁用了哪些功能，可以使用以下命令：
Get-WindowsOptionalFeature –Online | Where-Object {$_.State –eq “Disabled”} | Format-Table

If you need to disable a feature you can use the following:
如果需要禁用功能，可以使用以下功能：
Disable-WindowsOptionalFeature –FeatureName NetFx3 –Online
Disable-WindowsOptionalFeature –功能名称NetFx3 –在线

Of course, you will most likely be adding a feature which can be done like so:
当然，您很可能会添加可以通过以下方式完成的功能：
Enable-WindowsOptionalFeature –FeatureName NetFx3 –Online
Enable-WindowsOptionalFeature –功能名称NetFx3 –在线
That’s all there is to it.
