There are a number of things that can cause this. If the command prompt is popping up after a specific time then the most likely cause is the task scheduler. There are some Windows services and third-party applications that can make an indefinitely recurring task in your task scheduler. It can also be caused by a Windows service trying to download something from the internet and failing, thus, trying over and over again. Although rare but not entirely out of the question is malware. There are certain viruses that hide as a Windows own service/application and it might be one of those viruses trying to either run something or download something from the internet.
Method 1: Turn Off Office Tasks
The most cause of this issue is a scheduled task running in the background. So, the logical step is to start with checking the task scheduler. A lot of the applications create a scheduling task that runs periodically. Sometimes it might be a bug or simply bad design but sometimes it might be a malware scheduled to download information after a specific period of time as well. We will cover malware in method 3. In this method, we will have a look at Microsoft Office-related tasks because Microsoft Office is known to create a scheduled task that creates this kind of issue. So, follow the step given below
This should fix the issue. If it doesn’t, repeat the steps given above and disable the task named OfficeBackgroundTaskHandlerLogon as well. The command prompt shouldn’t come up once you are done.
Note: If this doesn’t solve the problem then you can open the Task scheduler and click the Task Scheduler Library from the left pane. You can look at the scheduled tasks from the list and disable any task that you might find odd or troubling. There can be multiple types of tasks scheduled to run that might be causing this problem. A lot of users noticed a RealDownloader update check task that was scheduled to run after every 47 minutes. So, if you find any of the scheduled tasks that seem odd then try to disable them.
Method 2: Using PowerShell
There are some commands that you can use in the Powershell to check if there is something getting downloaded or not. This will help troubleshoot whether the problem is because of some service or not.
Method 3: Check for Malware
Command prompt popping up can be an indicator of an infected system as well. Lots of malware and viruses tend to download information from the internet. A lot of the times they also disguise as legitimate services. So, if following the instructions in methods 1 and 2 didn’t solve the issue then the most likely cause is malware. So, here are the steps to detect whether your system is infected or not. If these applications find an infected file then make sure you get rid of it. Note: If you have Kaspersky or any other security application then either disable it or uninstall it before running the ESET online scanner. These are known to cause conflicts and your ESET scan might not complete.
