CreateJobObject.exe and CreateJobObjectTimeout starts a program (such as a batch file). That program and any programs started by that program will be terminated as a group.

This uses the inbuilt compilers in Windows 10 - there are three VB.NET compilers and three C# compilers - just copy each text file into the same folder and double click the batch file to make the program.
