Hi RedPlayzAndCreatez,
Welcome to Microsoft Q&A forum. I'm happy to help.
ProductName and DisplayVersion are safe to change in Registry. However, please make sure you back up Registry and make a restore point in case there's something wrong.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
More information about System Restore can be found here: System Restore - Microsoft Support.
I hope that above information is helpful to you.
