Bottom line... can i change the computer identifier to something new?

I am using a copy of a VM.vhdx to create a new secondary VM.  However, the computer identifier is the same on both after setting them up.  What do I need to do to create a new computer identifier?  Deleting and reinstalling Pulseway is not enough, it still shows up with the same one.  I assume somewhere deep in the registry I need to delete some things to stop this from happening.  

Thanks

If you are talking about Linux system, then you need to delete the following file: /var/pulseway/pulseway.id , but if you are talking about Windows system, then you need to delete the values for the following registry keys before you run sysprep:

HKEY_LOCAL_MACHINE\SOFTWARE\MMSOFT Design\PC Monitor\ComputerIdentifier
HKEY_LOCAL_MACHINE\SOFTWARE\MMSOFT Design\PC Monitor\ComputerName

These values will be regenerated automatically.
