Hello Patryk Szop,
Thank you for posting in Q&A forum.
You can perform a clean install. You need to boot from the install media in order to choose Home during setup.
For more information, please refer to detailed steps in the similar threads.
You can also try to downgrade Windows 10 Pro to Windows 10 Home.
Note: Please back up the Pro operating system and all the important data in advance before making any changes and operations.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
