Windows 10: CMD Window Flashes Briefly – Possibly Linked to svchost.exe?

Hi everyone,I'm encountering an odd issue on Windows. Every so often, a Command Prompt window flashes on screen for just a split second—too fast to read anything. It’s not consistent but happens periodically, and it’s been a bit unsettling.Restarting the computer doesn’t resolve it.To troubleshoot, I used an application called Process Monitor ProcMon to try and trace what might be triggering it. Using filters, I noticed some activity linked to svchost.exe around the same time the flash occurs. I'm not 100% sure it’s the cause, but it was the most notable process that stood out.This isn't the

Analyzing Svchost processes in Windows

Here's how to track down detailed information about any Svchost.exe process running in Windows 7/8.

a) You can use the Tasklist command-line tool to learn which services are running in a Svchost.exe. Just run cmd (command prompt) and hit

Tasklist /svc /fo list

Scroll through the list and find what you need. It's not quite intuitive so you can use third party programs with gui. See below:

b) You can use svchost viewer. Best utility. Note: to run this under XP you need .Net framework 2.0





c) Svchost Process Analyzer is another app for that.





d) And another app called Svchost lookup tool





e) And it won't hurt if you use Process Explorer and System Explorer.


It's never bad to keep your system under control, plus all these apps are portable no installation is required.

What does the svchost do?

Lots of Windows services are tied to the SVChost, and /or are listed as SVChost in the process list(s).

Unfortunatley with Vista, there's a lot more dependencies between the services, and thus you'll be FORCED to run more instances of SVChosts; unlike XP where things were more independent and you could disable more features resulting in less SVChost instances. That and XP and Vista are different.

Regardless of your Windows version, you can check out some service slimming guides or goto Black Viper's website and take his advice. Depending on your needs you may be able to cut down the amount of SVChost running, and save some RAM.

XP should never have an SVChost using 50mb. Vista however can.
