[BUG] Win 7 Security update causing system to spontaneous reset

[Aj2]

So, windows 7 machine. (running a windows 7 compatible scanner - windows 10 wont work here)

latest microsoft security updates (since about august last year) causes a spontaneous reboot (no bluescreen, just straight to black screen and bios) when ALL of the following conditions are met.

1. Network cable is plugged in
2. Device has a valid IP address and working gateway address
3. patch is installed
4. user has logged in.

so, if any of these conditions are not true, the machine works fine.

if we turn off DHCP server, and the machine does not pick up a working IP, it works fine.
if we hard code IP, without a gateway? fine
just unplug network? fine

Boot to logon screen without logging in? fine

uninstall the security update, works fine.

we have tried multiple net cards with no change

Client says he wont be needing the device this machine is controlling for much longer and not to worry about solving issue, but it is personal now.

Thoughts?

TIA

I would say if it is narrowed down to a security patch, you're at the mercy of Microsoft at that point, only thing you could really do is let them know and hope they fix it.

It's Win7, dead next Jan, unit should have been replaced / upgraded by now.

Remove the patch.
Block it.
Move on.
Or, spend a lot of time researching if you have time.
Win 7 is almost over.
