Ask HN: Why do all my Win10 devices popup random CMDs

1 points by mimsee 10y ago ↗ HN

I have a Win10 PC and a laptop and both of them are popping up CMDs (usually two at one time) once logged in. This has been going on for a while and my antivirus(es) cannot detect anything. The CMDs also come and go so quickly there isn't enough time to read what it says or to take a screenshot. I've also seen this happening on some of our school's laptops. What to do and should I be worried?

CMDs?

cmd.exe

Could be anything, but probably is nothing to worry about. For example, for the school laptops, they could mount a shared drive.

Get Autoruns (https://technet.microsoft.com/en-us/sysinternals/bb963902.as...), and check what gets run on login.

Unticking Windows Media Player solved it. No more CMDs on boot. Thanks!

Are your Win10 devices domain joined? Sounds like malware.
