Can anyone vouch for the free version of windows 10? Via the media creation tool

Solution
There is no "free" version.
Rather, it is the regular Win 10, just not activated with a license key.

No customization of the desktop or taskbar.
A randomly appearing watermark at the bottom right. That shows on top of everything.

Other than that, it runs just fine.
I have a long running Win 10 Pro installed, Unactivated.
Dec 8 2016.
Still running just fine.

The Insider concept has changed a bit.
Now, you DO need a real Win 10 license key. This is a very recent change.
You can install the Insider as a different system, but it does require a license.
