Let's assume the information about the Windows 10 key logging is true.
Access to this key logger data is the holy grail in computer hacking.
A dream of every "commercial" hacker. This means you can fully automated generate Fullz each at the moment $35 USD worth.
45 mio. (of 1.5 billion, data from 11-Aug-2015, strong growing) Windows 10 systems at the moment.
The average DNS bit-flip error rate is 1 in 100,000 requests. See Bitsquatting: DNS Hijacking without exploitation

Here is one thought-provoking quote from that dinaburg.org article:

Some machines control considerably more traffic than others. While a bit-error in the memory of a PC or phone will only affect one user, a bit-error in a proxy, recursive DNS server, or a database cache may affect thousands of users. Bit-errors in web application caches, DNS resolvers, and a proxy server were all observed in my experiment. For instance, a bit error changing fbcdn.net to fbbdn.net led to more than a thousand Farmville players to make requests to my server.

P And this are only 1 bit-flips. As it turned out multiple bit flips are even more common than single bit-flips.
This means at least 450 wrong DNS requests from this 45 mio. Windows 10 users. Per domain.
3 domains (nsatc.net, footprintpredict.com, microsoft.com) Wrong requests every day: (A record TTL):
nsatc.net=3 h, footprintpredict.com=0.5 h, microsoft.com=2 h == (24/3*450)+(24/0.5*450)+(24/3*450)==30,600

Not all DNS Bitquatting domains have equal value. The order of bit flipping probability is 0,6,(1+2),8,(3+13),14,12,15,(4+5),(7+9+11),10
The bit in position #0 is 100 times more likely to be flipped than one in position #10
If someone like to exact calculate what are the most likely single and multi bit-flip bitquatting names are, here: Observations on checksum errors in DNS queries are all the data you need to do this.

What single bit-flip bitquatting names are free and which are taken ?
(the taken and connected ones are listed with the IP and country)
[Editor's note: I am just listing a few of the more concerning Microsoft bit-flips in interest of brevity. Please see original submission for the very large full list..]

I'm totally surprised that not all of them are already taken.
Does Microsoft care ? Of course not.

    If your router doesn't let you change the hosts file and you don't trust the windows handling of hosts then you can just do what I did a while back. I set up a raspberry pi on my network and installed dnsmasq. It's configured to provide both DHCP and DNS services and makes use of the hosts blocking file in the parent as an additional DNS source. Upstream it defaults to running queries on 8.8.8.8 (googles DNS). I think switched off my router's DHCP and let the new raspberry pi take over. You can do the whole thing in an hour or so including reading the docs / configuring DNS Masq.

    Once that's done, you can block what you like and add in what you like e.g. aliases for DNS entries your ISP / country is blocking.

    Yes, you can. IPFire (a branch off of IPCop) is great and the work is done. Since IPFire is based on IPCop, the same instructions and methods will work.

    I use RPi/IPFire as network backup device paired with my cell phone (rest of the time, it is print server). So it main network is down, unplug from main network modem and plug in IPFire, nothing else changes. I do like the software and would like to use the lower power setup for main firewall, but with only 1 ethernet port (via USB) it is lacking for me through-put.

    If you have a router that is that bad to begin with I might suggest one of these first [google.com] then go and get a router that has good firmware from the factory or can have OpenWRT or DDWRT put on it.

      That's definitely easier to do in the US than in say Australia. I've looked quite a few times at the list of routers that support Tomato, OpenWRT or DDWRT and never seen a match with one that I can actually buy here. A lot of Aus is on ADSL, and since most of those don't even support ADSL / routers - it's a no show.
