Hi,

While this might be normal, if it happens constantly, it could be related to a driver, a system service, or software on your PC.

Another possibility is the presence of malicious software. You can test this by performing a "clean boot." If a Command Prompt (CMD) window opens, click on it to pause the output; this will allow you to see which process is attempting to start.

Performing a clean boot is also a good way to check whether the issue persists.

Hi,

If this only happened once, it is usually normal; it could be a service or driver update delivered via Windows Update.

If you are still unsure, you can run scans using Windows Security, the MSRT (Microsoft Malicious Software Removal Tool), and Malwarebytes to ensure there is no malware on your PC.
