How can I use Windows 10 unattended, without getting keylogged and sending everything to Microsoft?

I would really like to test the technical preview of Windows 10.
I don't want to just install a few programs on it and see if they work, I also don't just want to quickly check out the new functionality.

I want to use it as my actual main system for a few weeks/months (and yes I know you're not supposed to do that) meaning that some sensitive data like source codes to some of my projects will be on that machine.
I don't want to help Microsoft to improve Windows, I just want to experience all the system changes and brace myself as a developer up for what might be coming soon.
But from what I heard, everything you do on the machine is being sent to Microsoft.
Since it is only a preview, I really don't want to rely on their encryption etc and I simply don't want my files being sent over the Internet to anyone and I also don't want my keystrokes and my whole usage patterns to be sent to anyone.

So my question is: How can I use Windows 10 unattended, without getting keylogged and sending everything to Microsoft?

What I did so far:

I did not use the Express settings during the installation. I selected customize.
And here are the settings that I used:

[Off] Automatically get device drivers, apps and info for new devices  
[Off] Automatically update my apps  
[Off] Use Smartscreen [...]  
[On]  Send a Do Not Track request [...] in IE  
[Off] Use compatibility lists for IE [...]  
[Off] Send some location based data to MS [...]  
[Off] Send MS info about how I use Help [...]  

[Off] Use Bing [...] let MS use my search history, location and some acc info [...]  
[Off] In IE, use page prediction [...]  
[Off] Let apps use my name and picture  
[Off] Let apps use my advertising ID [...]  
[Off] Let Windows and apps request my location [...]  
[Off] Get better protection from malware by sending info and files to MS [...]  

I also did not create a Microsoft account or logged in into an existing one, I just skipped that stuff and went with a normal Windows account.
Then I installed Firefox, so I won't have to use IE.

What else will I have to do now?

Is there maybe a list of hosts/IPs that I could block using the hosts file?

I found an interesting open source tool on reddit which seems to be able to disable all the tracking stuff:
