While running command line processor “Console 2” for the Windows, why that command appears for a while and then disappears. What is the method of launching that substitute command as it also does not show any prompt line?
Command line processor on Windows (console 2)
Check your application log to the cmd window closing for the entry related that could be the cause why it appears and suddenly disappears. It could also be a corrupted server. To make sure you have no corrupt file or disk, start to run chkdsk /f on the volume. Frequently make review on your event viewer logs for clues.
You can also just scan your computer using antivirus, your system could just be infected by a malware or a virus.
If you still suffering for that problem, it is good to reformat your computer so that other files will not be affected and have them secured for intrusion.
I hope this can help
