Microsoft’s own test team disbanded.
It has become a tradition that when Microsoft releases the next update for the Windows 10 operating system, users should prepare for unpleasant surprises.
The Windows Update mess began with the release of the Windows 10 October 2018 Update a little over a year ago. Then the update led to the removal of documents, photos and other files from computers. After that, the May update of Windows 10 May 2019 went more or less smoothly. However, monthly updates were again problematic. For example, there was an error with excessive load on the processor, broken Start menu and even the taskbar, problems with connecting to the Internet, and so on.
The November 2019 Update, a big fall update, has broken Explorer. And a recent critical update to Windows 10 is causing a blue screen of death.
According to former employees, one of the main things is that Microsoft has changed the testing process for updates. Once the company had a whole team to test updates with separate “squads” for different directions, such as drivers or the interface. All team members discussed flaws in daily meetings. In addition, they tested updates both automatically and manually on real, rather than virtual, systems.
In 2014, Microsoft got rid of this team and stopped testing updates on real configurations for most cases.
In addition to using virtual machines, Microsoft now relies on the Windows Insiders community of testers, which is mainly made up of enthusiasts and fans.
