Windows 10: How to getting back my Windows 10 Home

So, i have this laptop since 2018. I brought it from store, Windows 10 home included, also activated with a digital license. Now is the problem, my friend borrowed my laptop for his education. And without me knowing, he upgraded my Windows to Windows Pro without any product key! My poor Windows has became a non-genuine copy! How do i get my Windows home back? I don't even remember which Microsoft account logged in my laptop before. Does a re-install a Windows home will fix it? Ugh fool friend!

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
