Doing these random changes is not going to lead us to a solution. Undo all the changes that you have done to your run.bat file, use the run.bat file which you downloaded from JBoss then try running it. 

When you run into that error again follow the instruction that i mentioned earlier (which are as follows) :

In the past week, there have been a couple of posts where similar issue was observed which resulted in the run.bat file terminating without any messages. The cause for that behaviour was turned out to be JAVA_HOME value not being properly set. In your case though the JAVA_HOME value and the output of %JAVA% -version look good. So that does not seem to be the issue.

Are you sure the 'findstr' is be on the PATH. You can find it under  windows\system32 folder on your system. If you dont have it in the PATH then you will have to add it as follows(just an example):

Once you have successfully ruled out these 2 probable causes, we will be able to move forward.
