There are a few free tools around capable of changing the volume serial number and one of them is called Hard Disk Serial Number Changer. Some people said that it is impossible to change it, but we will show you that there are ways to change both volume and hard coded serial numbers for your hard disk. If you do a simple search in Google, you’ll find tons of information about to change your hard disk volume serial number, but not the real hard disk serial number that is hard coded into the hardware. If your Windows has been activated using a product key from a sticker it will probably ask for the key again after a reboot and will need reactivating if you change the volume serial number on the system drive. The volume serial number changes every time you format the partition and Windows also uses this value during activation so you can’t simply move your install from one partition to another. Type dir and it will show a different serial number even if the volume is on the same physical hard drive. The second line shows your volume serial number for the system C partition. Other than that, some licensing system also uses the hard disk serial number to generate a unique hardware ID which is then used to generate an external license file to activate the software.Ī simple way to find your current hard disk volume serial number is to open a command prompt (Win key+R and type cmd) and then type dir. So now they’ve started to ban the CD-Key. It used to ban the hard disk serial number but no longer does that since there are ways to spoof and temporarily change the so-called hardcoded serial number. Some multiplayer games that implement the PunkBuster anti cheat system get cheaters off the server using hardware bans.
