Why does cmd.exe pop up on startup?

The Command Prompt (cmd.exe) popping up on startup can occur for various reasons. Here are a few possible explanations:

1. Some programs or scripts may be configured to run during system startup and open a Command Prompt window for logging or executing specific commands. This behavior is often seen with system management tools or custom scripts.
2. Certain malware or viruses may create startup entries that launch cmd.exe to execute malicious commands or scripts. Regularly scan your system with reputable antivirus software to detect and remove potential threats.
3. If a user modifies the startup settings or creates custom startup scripts, cmd.exe may be configured to open on startup as per their preferences.
4. Sometimes, configuration errors or conflicts within the Windows operating system can cause cmd.exe to pop up during startup.
