when I rename it to .txt it stays as normal
Well, if you renamed it correctly, it should be changed to .txt.
I have the feeling, I don't quite understand you.
Maybe you have the same issue as me. For me, the .txts get replaced by the usual exe's when launching R6 the next time.
That's why I just disable BE i the Task Manager.
I used this command from a friend here, it passed me, now the services are back to work,
