Command Prompt appears and disappears on Windows 10

Command Prompt is used by applications to install or update components silently. If everything works fine, they sometimes appear like a flash and be gone. At other times, it appears and disappears. But if they appear multiple times, then it becomes a problem. This post will provide some guidance on what you can do in this situation and get rid of the Command Prompt which appears and disappears on Windows 10.

Command Prompt appears and disappears

It is important you get hold of the program name that appears when the Command Prompt appears. If it appears multiple times, then you should have a chance to notice it. If you can make note of the program name, check if it has been installed properly and that all its processes have been completed. If not, you may re-install the program and see.

If you cannot do that, it will take a longer time to figure it out. You need to do the following:

• Check Task Scheduler
• Update .NET Framework
• Check for Malware

You will need admin permission to try the solution and fix the problem.

1] Check Task Scheduler

Most of the background processes, including updates, are scheduled through Task Scheduler. If they are running scripts through Command Prompt or PowerShell, it may appear briefly. Usually, these scripts run once unless they fail to complete the process. In that case, they are set to rerun the script. So if you see them appear and disappear multiple times, then this is the reason.

To figure out, you will have to open the Task Scheduler and then go through them. Each task has a Last Run Result column. If it’s anything other than 0x0, then it is an error.  If the prompt keeps appearing at a certain time of the day, it will make it easy to identify.

Note: To open Task Scheduler, type the same in the Start menu, and click on it when it appears.

2] Update .NET Framework

Installutil.Exe Command Prompt Flashes. What Does This Mean?

Installuitl.exe is a command-line utility that is related to .NET Framework applications. It may be trying to update or install a component, and the command line keeps appearing. If you can cite it when the Command Prompt appears, you need to update to the most current version of the .Net Framework package. Once done, the flashing Command Prompt will not appear anymore.

Check Office Subscription

Like the .NET framework, Office Subscription is also known to cause a similar problem. Task Scheduler holds an Office Subscription Maintenance task, which runs every day to ensure that the Microsoft Office Subscription licensing is current. If it is not able to validate, then it will rerun.

Open the Task Scheduler, and navigate to Microsoft > Office. Locate the subscription maintenance task, and disable it.

3] Run Windows Defender

If nothing else works, you may want to run Windows Defender or your Antivirus to scan for malware. Make sure to ruin it when in safe mode so it can easily be removed. You can also use the online scanners.

While the problem is tricky, I hope the post helps you.
