@RandomGOTI does this happen for you when runnying anythign or some specific software?

[ghost]

I got it too when I was running Edge.

BTW: Edge does not close properly if it has been running for a long time

[DavidXanatos]

did you do anything special? and @mysteriously does that happen to you on windows 7 or 10?

[RandomGOTI]

@DavidXanatos for me it happens with anything (incl. run > run program context menu , start terminates and the 2 processes linger)

[ghost]

It happened few times in a row on same day. However it was few days ago so I don't recall anything specific. Win 11 22H2

Oh, I think it could happen when I was running the same browser (Edge) installed on host machine in few sandboxes at the same time

[DavidXanatos]

Ok so @RandomGOTI issue is fixed its a generic incompatybility with windows 7 accidently introduced in one of the recent builds.
@mysteriously you have a different issue wof that I'll need a way to reproduce it reliably here.
