re installing windows on my laptop

I have to re-install windows on my laptop and am woried as i have read somewhere that you can only register pscan once on each computer and once its deregistered it cant be registered again.
can you please tell me if re-installing will cause problems,

When you re-install Windows and re-install pscan, it should detect the rebuilt Windows as being the same computer and not ask you to register again, so it won't use another license.

Please go ahead and re-install Windows if you want to.

It is a completely legitimate thing to do, and it should work, and if it doesn't I will give you full support to fix the problem. That's a 100% promise.

Thanks for your help all done and the good news is my Pscan is still working. the bad news is my Toughbook still wont connect to WIFI so I have to connect to the Lan to get updates.
