为什么出现161（无效路径错误）？

我有一个驱动例程于system32\\drivers\\hellowdm.sys
以添加注册表方式安装，注册表内容如下
其中\"ImagePath\"内类容为REG_EXPAND_SZ类弄的＂system32\\drivers\\HelloWDM.sys＂

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\HelloWDM]
\"DisplayName\"=\"Hello WDM\"
\"Description\"=\"HA HA\"
\"ErrorControl\"=dword:00000001
\"ImagePath\"=（hex2):53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,44,00,52,00,49,00,56,00,45,00,52,00,53,00,5c,00,48,00,65,00,6c,00,6c,00,6f,00,57,00,44,00,4d,00,2e,00,73,00,79,00,73,00,00,00
\"ObjectName\"=\"HelloWDM\"
\"Start\"=dword:00000003
\"Type\"=dword:00000001

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\HelloWDM\\Enum]
\"Count\"=dword:00000000
\"NextInstance\"=dword:00000000
\"INITSTARTFAILED\"=dword:00000001

重启系统后，执行NET START HelloWDM,系统报告161错误，无效的路径，请问错误在哪里？应如何解决？

路径字符串的最前面添加\"SystemROOT\\\"试试

出现错误３，系统找不到路径！
