Your BIOS serial is saved via software, not hardware. Like anything else that's software based, the BIOS serial can be changed. The serial number data, as well.

I'm new with batch file and wmic and after researching StackOverflow I've found few answers which overlap but not producing expected output when put together. Problem: Create a batch file to change computer name (not on domain):. use wmic bios get serialnumber and assign the value to the variable compname, then display the value of this variable;. change computer name to the value of the variable compname; So for 1.: FOR /F%%F IN ('wmic bios get serialnumber') DO ( SET compname=%%F ) ECHO%compname% Followed by 2.: WMIC computersystem where name="%computername%' rename name=%%compname%% edit: got a 1.

Part correct - works as expected - fetching serial number and displays the variable's value. However part 2. Still throwing errors: O: wmic computersystem where name="TOM-PC' rename NAME= Invalid named parameter list.

Hint:::= where::= = If I understand correctly - the NAME=. Part of the last command don't recognise variable initialised above. So how to use a compname as a parameter for wmic command? Edit.2 'Why are you using doubled% signs in name=%%compname%%?' By aschipfl - I reverted to my original question - used double% and now getting different error - 87 which tells me more about the problem. Using singles% produce the error listed above. I'm not sure if the problems lies in single or doubles% or somewhere else.

Edit.3 Further research shows that wmic bios get serialnumber returns in fact three values each in new line C: Windows system32wmic bios get serialnumber SerialNumber BY3VF02 that is - SerialNumber string followed by actual serial number in new line and last one with just empty line. So (I hope) the final questions - how to assign only the second value to my variable please? Give a try for this batch code: @Echo Off For /F 'tokens=2 Delims'%%A In ('WMIC Bios Get SerialNumber /Value') Do ( For /F 'Delims="%%B In ('%%A') Do ( Call:RenamePC '%%B' Call:Ask4Reboot ) ) pause & Exit /B::.:RenamePC WMIC ComputerSystem where Name="%ComputerName%' call Rename Name="%1' Exit /B::.:Ask4Reboot ( echo Set Ws = CreateObject('wscript.shell'^) echo Answ = MsgBox('Did you want to reboot your computer?' echo,VbYesNo+VbQuestion,'Did you want to reboot your computer?'

^) echo If Answ = VbYes then echo Return = Ws.Run('cmd /c shutdown -r -t 60 -c 'You need to reboot in 1 minute.' ' -f',0,True^) echo Else echo wscript.Quit(1^) echo End If )'%tmp%%n0.vbs' Start ' '%tmp%%n0.vbs'.

Nal Have at it, Lad. Pass it on as you see fit. The stuff I send was not mine to start and I have no proprietory interest in it, so any one is free to pass it on. The 'paper clip'Doc came from a website where it was a freeware download, the DST software is from Dell Disks not readily available to the public, and a few Text files, pics from me and other users are the balance. The other thread where I posted about Passwords and Service Tags is now closed down by the moderators because of its very large size. Sysbrd Ser # Can somebody please tell me if each system board has a unique serial number that is coded into the board? It is in the Bios, but was wondering where it comes from.

Is it purely coded or is it hardware? This is on Dell desktop units I'm wondering if there are browser pages that pull this information when you post or download. It would seem that if you are a registered owner with Dell, they can not only identify your isp, but also who the computer is registered to. Does anyone know if Dell shares this information with the government? Does anyone know how this bios information can be shielded from network traffic?

Dell does not tell people about this information, but it is easy to find. Ok Dell puts the serial number in the eeprom and on a sticker on the desktop or laptop itself. The way dell knows what your serial number is is a program called eeprom reader that they install on all new dells. If you remove that progam, erase the eeprom and remove the sticker. No one can tell what the old serial was. Now some say they can find out by your mac address. This is true and not true.

If you connect with the modem it is true, but if you connect via cable modem or router the only mac address that touches the net is the one from the cable modem or the router. No mac from the computer will pass from the router. If anyone has more info for him please fell free to post it.
