If you see Command Prompt window pop-up too often, it means something might be wrong. Windows has processes that need to run periodically, or just every now and then. A good place to look is the Task Scheduler. This is especially if the Command Prompt window flashes when the system is left idle for a few minutes. If a Command Prompt window opens up and closes quickly, it could be due to automatic maintenance task (s) kicking in. Would you be worried about this? Does windows / HP support assistant sometimes open command prompt windows for routine maintenance/updates? It is the fact that it has occurred on both machines which particularly concerns me. If the cause of the window is a system process. The following are the common reasons why a Command Prompt window would open and close automatically. I have run McAfee scans which have detected no problems. Theres this black screen that keeps popping up while I do my work, or anything on the computer. Again I noted a (differently named) nexus in my network. Again it was shortly after switching the machine on. I didn't catch it but think it was different from the previous episode. I was using the other laptop about 5 days ago, when again the command prompt box briefly flashed up and disappeared. I think HP support assistant may have been doing something at the time. At the time I didn't worry as I thought it was a maintenance process, and assumed I was picking up a neighbour's device on my network. I happened to have the windows 8 network folder open and noted an unknown Galaxy nexus device in my network, which disappeared shortly after. They closed very quickly but I think I caught something flike '1 files copied'.

Having switched it on about 5 minutes previously, I was looking at webmail when 2 command prompt boxes popped up in quick succession. Windows 10 - Every 10 minutes or so, a cmd prompt, (or little black DoS window) flashes on my computer. I was using one of the laptops 12 days ago. CMD prompt window pops up and instantly disappears. Both loaded with HP support assistant.Īpologies in advance for the lack of info and for my complete lack of computing knowledge. Hi, I have 2 laptops, both identical: HP Pavilion with Windows 8.1 and McAfee LiveSafe internet security (McAfee antivirus and antispyware version 17.6).
