2 个解决方案

#1

try this:

尝试这个：

@echo off &setlocal
for /f "tokens=2*" %%a in ('reg query HKLM\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile /v EnableFirewall') do set "var=%%b"
if "%var%"=="0x1" (do this) else do that

#2

This should work for you:

这应该适合你：

for /f "tokens=3" %%x in ('reg query HKLM\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile /v EnableFirewall') do set FWSTATUS=%%x

If testing from the command line, change the %%x to %x instead.

如果从命令行进行测试，请将%% x更改为％x。
