for /f "delims=" %%i in ('findstr /g:black_list.txt /v list.txt 2^>nul') do (
echo %%b\Bin\x64\DISM10\dism.exe /image:%%b /Remove-Capability /CapabilityName:"%%i"
%%b\Bin\x64\DISM10\dism.exe /image:%%b\Mount\Install /Remove-Capability /CapabilityName:"%%i"

black_list.txt 内容为空，就失效了
怎么解决呢，

虽然black_list.txt随便写点就解决了，但这bat不完美

回复 1# hentai87

在for命令上面加一句：

more "black_list.txt" | findstr "." >nul 2>&1 || goto :eof

试了，没用，下面是完整代码

@echo off
cd /d %~dp0
%1 start "" mshta vbscript:createobject("shell.application").shellexecute("""%~0""","::",,"runas",1)(window.close)&exit

setlocal EnableDelayedExpansion

for /f "delims=:" %%a in ('findstr /n msmg设置 ..\set.txt') do set n=%%a
for /f "skip=%n% delims=" %%b in (..\set.txt) do (
for /f "tokens=1,2* delims=: " %%A in ('%%b\Bin\x64\DISM10\dism.exe /image:%%b\Mount\Install /Get-ProvisionedAppxPackages') do (
if "%%A"=="PackageName" (
cd. >list.txt
echo %%B>>list.txt

more "black_list.txt" | findstr "." >nul 2>&1 || goto :eof
for /f "delims=" %%i in ('findstr /g:black_list.txt /v list.txt 2^>nul') do (
%%b\Bin\x64\DISM10\dism.exe /image:%%b\Mount\Install /Remove-ProvisionedAppxPackage /PackageName:"%%i"
))))
endlocal
pause
exit /b
