Windows 10: Windows 10 deactivated version

I've been receiving a lot of conflicting answers from various other places where I ask this, so I decided to come straight to microsoft. I'd most prefer somebody official, a staff member, or someone like that answer this. It's about using windows 10 deactivated. On the microsoft site itself, I see the ISO file for the windows 10 disc image here,

I've been told using the deactivated version, that is not using a licensed key costing $100 or more, simply adds a watermark in the corner and removes some customization options, but that's it. I've also been told doing this is illegal by some, and that it isn't by others, or that it will fully shut down and become unusable after about a month. I want a final, definitive answer on whether or not I can simply download this to a USB, install it, and boot it legally without buying a key.

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?
