Windows 10 May 2020 took 15 months to develop, and there are still a number of known issues

Microsoft today officially released an update to Windows 10 May 2020 features. In fact, it has been tested in the Windows Insiders project for 15 months, and the RTM version was released in December last year and has been polished ever since.

Windows 10 May 2020 took 15 months to develop, and there are still a number of known issues

The reason the test ingress is so long that Microsoft has adjusted its release strategy for feature updates, which have become more cautious after a major error in the Windows 10 October update. After the 2019 adjustment, the pace of the introduction of new features has been greatly slowed in an attempt to bring a more stable system experience to users.

But that doesn’t mean there’s nothing wrong with Windows 10 May 2020 feature updates, including the known issues listed in the official list:
