Windows 10: Install W11 Enterprise on a W11 Pro personal computer

Hello:I have a personal laptop with W11 Pro on it. I want to install W11 Enterprise on it for better security and safety. What are some of the problems I can run into by doing this?

:)

 

W11 File Explorer?

Thank you. I notice it only says W11. Will it realise I have W11 Pro and install the correct version?

 

W11 File Explorer?

I notice you say download the W10 ISO, however I have W11 Pro so is this correct? Will this affect my installed programs? The W11 Pro was pre-installed on the PC by Dell. I have no product keys, etc, will they be needed (I think the activation state says it is activated with a digital license linked to my Microsoft account)? Obviously a little uneasy that I have to mess with the Windows installation on a brand new PC with no W11 Pro backup details.

 

Surface Pro 3 with Windows 11 Insider Preview OS vs. Surface Pro 4 with W10 Pro that cannot upgrade to W11

Two questions:

1. My Surface Pro 3 continues to download and install W11 updates on the Insider Preview Channel. How long might I expect to have access to updates? In other words, will I lose access and be forced to revert to W10?
   
2. Can I enroll in Windows Insider Preview on my Surface Pro 4 and upgrade to W11 Insider Preview?
   

I'm finding more and more to like about W11 and would certainly prefer to continue to move forward, not backward.
