How to find CPU serial number

**tech291083** · October 6th, 2012

Hi,

I am using win 7 Home Basic 64+ bit OS. I do not want to dismantle the pc and check the serial number of the cpu. Is there a tool that can do so? Thanks.

You could boot a live CD and then run lshw to see if that gives you the right information.

Code:

sudo lshw -class processor

That's a cool trick. Didn't know you could find the serial number with that. Well sort of...mine's funny:

Code:

*-cpu                   
       description: CPU
       product: Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz
       vendor: Intel Corp.

       configuration: cores=6 enabledcores=6 threads=12

Since I built it, I guess I'm the OEM. Now I have to think of a serial number, I guess....

Thanks for the reply. But I am a little confused here. Are you talking about Win 7 live CD? If yes, then I do not have one with me. If you are talking about a live CD of some Linux distro then I migh have one using which I can do the command you have talked about. I only have Win 7 installed on this HDD and no other OS. Thanks.

Hi,

Jus wondering if there are other commands to know the serial numbers of other parts in a pc namely HDD, motherboard, RAM etc. This can be really helpful when you do not have the sales receipt. Thanks.

You can try one of the many system infor utilities in windows.
These are all freeware http://www.techsupportalert.com/best...on-utility.htm

As for the CPU serial number that info might not be available to you. Post PIII cpu many manufacturers disabled this in the cpu or BIOS.

Yes, I was thinking in particular one of the Ubuntu Desktop (live) CDs. Other Linux distros have live CDs that might also be of use. There is no need to install, yet, just run the Live session.
