Microsoft Windows 10 is the latest edition of Microsoft Windows. The tech giant released '10' to the public August of 2015. It is the first release after the failed rollout of Windows 8. The first time Microsoft has released a limited-offer free upgrade.
Most people that have a valid copy of Windows 7, 8 or 8.1 were eligible for a free upgrade for one-year following the release date, July 2016. Surface models such as RT are not eligible for the 10 upgrade. Enterprise editions Windows 7and 8 upgrades to Windows 10 are not free.
Security and Privacy Concerns
Windows 10 may be a free upgrade for most current Windows users, but there are major security and privacy issues in the operating system itself. However, the EULA or End User License Agreement states that Microsoft has access to not only the metadata of your files, but their full content, how often you access them, for how long you view them, and when, just for starters. There are techniques to disable obvious built-in spyware on part of Microsoft within the operating system, but as Windows is a closed-source operating system, no user no matter their skill at computing can be sure of their privacy protection. At this point in time, most conservative and libertarian (as well as classical liberals and even constitutional progressives) should avoid Windows 10 at all costs. Migrating to GNU/Linux is a viable and sensible option if you care about your rights to privacy and security on your personal and work computers.
Microsoft has announced that Windows 10 will be its final release of the Windows operating system. This does not mean that Windows will no longer exist, but simply that from now on, they intend to release updates and patches to Windows 10 only. They intend to avoid any further systems that must be installed onto a blank partition.
