Device List Change

Hi new here so excuse me if iam asking a silly question
I have had a Device List Change Alert and not sure what it means

What could “Device cupuz136” was added mean is it some sort of danger ?

Hello Peter,

It looks like that’s a driver for a popular HWM/Benchmark software called cpuid according to this link I found but you could upload it to just in case.

Here’s a useful guide that might help you

Hello Ken
Thanks for your help
I have some further information. When restating the computer next morning i had anther Device List Change Alert this time
Device cupuz136" was Removed

I also found this info from “Google”

/Cpuz136_x64.sys is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices. This means that a driver has direct access to the internals of the OS, hardware etc.

So not sure what happened however I have searched computer Registry and Files can find no evidence of this file or driver, done a complete Microsoft Security Essential and Maleware Pro scans which both came up clean.

Bye the way great program keep up the good work


I think it could be related to sleep stop error “0x00000001”
