windows自带的WMI服务损坏(C#程序需用到此服务)，处理方法：
1）新建文本文档，将以下内容拷贝放入文本中:
net stop winmgmt
net stop winmgmt
winmgmt /resetRepository
@echo on
cd /d c:\temp
if not exist %windir%\system32\wbem goto TryInstall
cd /d %windir%\system32\wbem
net stop winmgmt
winmgmt /kill
if exist Rep_bak rd Rep_bak /s /q
rename Repository Rep_bak
for %%i in (.dll) do RegSvr32 -s %%i
for %%i in (.exe) do call :FixSrv %%i
for %%i in (.mof,.mfl) do Mofcomp %%i
net start winmgmt
goto End
:FixSrv
if /I (%1) == (wbemcntl.exe) goto SkipSrv
if /I (%1) == (wbemtest.exe) goto SkipSrv
if /I (%1) == (mofcomp.exe) goto SkipSrv
%1 /RegServer
:SkipSrv
goto End
:TryInstall
if not exist wmicore.exe goto End
wmicore /s
net start winmgmt
:End
cd /d %windir%\system32\wbem
for /f %%s in (‘dir /b *.dll’) do regsvr32 /s %%s
for /f %%s in (‘dir /b *.mof *.mfl’) do mofcomp %%s
wmiprvse /regserver
winmgmt /regserver

2）然后另存为，保存类型选择“所有文件(.)”,文件名称中输入“1.cmd”，然后“确定”保存。

3）选中1.cmd文件，右键“以管理员身份运行”，在弹出命令窗口输入“y”敲回车键，等待命令执行完成，重启电脑再试。
