Task: 删除HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_0XXX&PID_0XXX Key Tree
首先第一想到的使用PS Script来删除:
Remove-Item -Path 'Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_045E&PID_07DC'
但是发现如果想删除USB Enum的话需要很高的权限，即使使用Admin权限，也遭到拒绝。
Remove-Item : Requested registry access is not allowed.
At D:\Debug_Local\RemoveRegistry.ps1:2 char:1
+ Remove-Item -Path 'Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\US ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : PermissionDenied: (HKEY_LOCAL_MACH...rolSet\Enum\USB:String) [Remove-Item], SecurityException
+ FullyQualifiedErrorId : System.Security.SecurityException,Microsoft.PowerShell.Commands.RemoveItemCommand
随后开始考虑用C#程序来删除。同时安装为Windows Service来获取System权限，来删除之。
foreach (var registryKey in usbRegistryList)
{
string keyPath = string.Format(@"SYSTEM\CurrentControlSet\Enum\USB\{0}", registryKey);
using (RegistryKey key = Registry.LocalMachine.OpenSubKey(keyPath, true))
{
if (key == null)
{
this.log.Append(this.GetCurrentDateTime()).Append(string.Format("The key {0} does not exist!", key)).Append(Environment.NewLine);
}
else
{
try
{
foreach (var subKey in key.GetSubKeyNames())
{
key.DeleteSubKeyTree(subKey);
this.log.Append(this.GetCurrentDateTime()).AppendFormat("The sub key {0} is removed sucessfully!", subKey).Append(Environment.NewLine);
}
}
catch (Exception ex)
{
this.log.AppendFormat("Error is found during removing key {0}. Details:{1}", key, ex.Message).Append(Environment.NewLine);
}
}
}
}
