Windows 10 is a Spying Machine
Windows is not a secure nor a private operating system platform.
I couldn't recommend it to anyone concerned about the security of their computing platform, or, the confidentiality of their personal private information (PPI).
It cannot be hardened or made secure so long as it is connected to the public Internet.
If you use it, you are unwittingly transmitting PPI, location data, and system data to Microsoft, even if you attempt to harden the o/s through enabling its privacy settings.
Out of the box, Windows 10 violates your privacy and transmits information to Microsoft.
Curious about what Windows collects about you? Here's an analysis.
Windows 10 transmits confidential information to Microsoft over 5,500 times a day.
Windows 10 search features keep transmitting PPI even if disabled.
Even when instructed not to transmit data to Microsoft, the o/s does so.
Extensive telemetry data cannot be prevented from being transmitted to Microsoft.
When you encrypt the drive with Bitlocker, the decryption key is sent to Microsoft.
The EFF continues to hound Microsoft to address their behaviors without response; Microsoft continues to disregard user choice and violates their privacy.
Google felt to publicly disclose a Windows 10 vulnerability before Microsoft, because they refused to take action; they did it to protect their users while Microsoft stalled.
Microsoft's operating system is constantly susceptible to zero-day flaws and attacks; famously, a Russian-created zero-day attack mounted by Russian intelligence services were used to attack the DNC.
If you're concerned about security or privacy, one cannot honestly look at Microsoft's offerings and consider them a serious option.
