Considering the history of MS and how frequent issues like this happen, it is no wonder everyone is screaming at MS. I honestly wonder how well they test their software considering the frequency of critical issues every update.

Back in 2014/2015, Microsoft employed an entire team that was dedicated to testing the operating system, builds, updates, drivers, and other code. The team consisted of multiple groups that would run tests and discuss bugs and issues in daily meetings. Tests were conducted manually by the team and through automated testing, and if tests were passed, would give the okay to integrate the code into Windows.

The teams ran the tests on “real” hardware in a lab through automated testing. The machines had different hardware components, e.g. processors, hard drives, video and sound cards, and other components to cover a wide range of system configurations, and this meant that bugs that affected only certain hardware components or configurations were detected in the process.

Microsoft laid off almost the entire Windows Test team as it moved the focus from three different systems – Windows, Windows Mobile and Xbox – to a single system. The company moved most of the testing to virtual machines and this meant according to Berg that tests were no longer conducted on real and diverse hardware configurations for the most part.

“By putting devices on the Current branch for Business, enterprises will be able to receive feature updates after their quality and application compatibility has been assessed in the consumer market, while continuing to receive security updates on a regular basis,” wrote Jim Alkove, director of program management for Microsoft’s enterprise group, in the Jan. 30 post.
