Cleverbridge reference number

Pisze z prośbą o pomoc by otrzymać numer referencyjny cleverbridge ponieważ musze jedną rzecz sprawdzić. dlatego iż ja restartuje laptopa a nie wiem czy jak zrestartuje to czy będe mógł wpisać znowu swój klucz licencyjny. a chcaiłbym poprostu usunąć swój laptop i dodam go na nowo jak zrestartuje. jak mam to zrobić

Maybe it’s a translation error but Restarting a laptop does not mean your software licences will be lost.
Do you mean you are Reinstalling Windows?

Anyway:
Your licence key will be shown in CCleaner itself.
Options>Licence Key in CCleaner v6
Settings> My Subscription in CCleaner7

If you do need to look up your CCleaner licence key then use this tool: CCleaner.com - License Lookup

Once you have your key noted down then just do whatever it is you are doing.
If it means that you have to reinstall CCleaner later then download and install CCleaner Free from the builds page v6.39 or v7 your choice, and simply enter your key to activate it as Pro again.

You don’t need your Cleverbridge number to install/reinstall and activate CCleaner, but if you want to look it up then use this: Customer Support Contact Page
