运行此命令以查询(A)存在且(B)不存在的服务导致：

(一个)

C:WindowsSystem32>sc query W32Time

SERVICE_NAME: W32Time
        TYPE               : 20  WIN32_SHARE_PROCESS
        STATE              : 1  STOPPED
        WIN32_EXIT_CODE    : 1077  (0x435)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

(B)

C:WindowsSystem32>sc query nothere
[SC] EnumQueryServicesStatus:OpenService FAILED 1060:

The specified service does not exist as an installed service.

因此,您可以在尝试使用以下内容删除它之前测试服务的存在 – (原谅令人厌恶地使用FOR语句,我不确定如何将sc命令的输出捕获到变量或在IF声明中使用它) –

set svcname=W32Time
set svc=exists
for /f "delims=" %%o in ('sc query %svcname% ^| find "FAIL"') do set svc=notexists

if "%svc%"=="exists" sc delete %svcname%
