Windows 10: Windows 10 changed versions and deactivated?

Hello,
My digital copy of Windows 10 Home Insider Preview has suddenly changes to an inactivated copy of Windows 10 Enterprise Insider Preview. I haven't used an activation code. I am running windows on a Dell Inspiron 13" 7391 running a Core i7 10510U and an integrated graphics card from Intel's UHD lineup. How can I change my version back with out paying, the laptop was £999, I can't afford to pay anymore to get this sorted. And I have school tomorrow.

:)

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

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

Deactivating Windows 10

Hello.

If I deactivated my version of Windows 10 pro, and reinstalled it on the same PC, will I be able to use the same product key again on the same machine? And are there any steps I should take prior to deactivation, in order to ensure that the product key
can be used again?
