Resetting macbook pro

Hi everybody,
I am about to format my macbook because it has the problem of suddenly turning black and I have often to shut it down manually.
I just wanted to know if, after having formatted the mac and reinstalled parallels, I can simply paste the .pvm file in its usual location and the virtual machine will continue working as usual.
Otherwise, do I have to deactivate the product keys of my windows softwares when I format the mac?
I don't know if, once pasted the VM in the formatted mac, I will have any license problems with the softwares contained in the VM.
Thank you very much for your help!

If your virtual machine is not Boot Camp based then you will be ok, just copy the .pvm file back and run you virtual machine as usual.
