I am trying to run a batch file in windows 8.1, when i run the batch file runs at first but closes so fast that you can't see its contents, you can't even see if its doing what you tell it to. Since the file does run but closes fast, i thought of adding pause. Adding pause did not fix the problem. I am not sure if i have to change my keys on regedit, or i have some kind of malicious software  that needs to be fixed  ( I think i have no malicious software, i  have run security scan many times nothing showed up, I had a Trojan horse, Trojan.Gen2, long time ago but the Trojan got quarantined?) I originally had windows 8 but upgraded to windows 8.1. 

Help Please! I don't Know what to do!!!

Hi Glogikon.

Could you post its code here?

don't Know what to do!!!

How about opening a cmd window (aka Command Prompt) and starting your "batch file" there?   <eg>

Hi Glogikon,

"I am trying to run a batch file in windows 8.1, when i run the batch file runs at first but closes so fast that you can't see its contents, you can't even see if its doing what you tell it to."
According to my experience ,it is a normal symptom .Did the bat file run well before ?
Have you tried to run the command one by one in the bat file from a command line ?Have you tried to run the other bat files which including a output to have a check ?
If it is possible ,please post the command of the bat file here .We will make a test for you .

To check whether the bat run well ,this link may be useful:

" I think i have no malicious software, i  have run security scan many times nothing showed up,"
We can try to work with the following official free tool to have a check .It is recommended to run it in a safe mode to improve the quality of the scanning.
