(WPF, Service) 删除注册表中的USB Enum值.
Task: 删除HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSBVID_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_MACHINESYSTEMCurrentControlSetEnumUSBVID_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_LocalRemoveRegistry.ps1:2 char:1 + Remove-Item -Path 'Registry::HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUS ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : PermissionDenied: (HKEY_LOCAL_MACH...rolSetEnumUSB: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(@"SYSTEMCurrentControlSetEnumUSB{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); } } } }
