You can use a Simple Batch File. Open Notepad and copy/paste the script below into a blank document. Save the file as BLOCKALL.BAT. Now copy that file to the same directory as the EXEs you want to block and double click it. It will add outbound rules to advanced Windows Firewall settings blocking all EXEs in that folder and sub-folders as well. …

BLOCKALL.bat

@ setlocal enableextensions 
@ cd /d "%~dp0"

for /R %%a in (*.exe) do (

netsh advfirewall firewall add rule name="Blocked with Batchfile %%a" dir=out program="%%a" action=block

)

Thanks man, this is very useful
