It is unclear why Microsoft had to wait until after the launch release this list of known issues and why they could not be addressed when Windows 10 version 2004 was tested. Since the list is already live, it can’t be due to customer complaints either, as it’s too early to start that process. We can only hope that that process won’t bring more bugs in the just released Windows 10 May 2020 update.

Windows 10 version 2004 is the first update to be released under the new direction of Panos Panay. Many hoped that this would finally end the era of buggy updates for Windows 10. While users are sure to criticize this list of known issues, it must be admitted that the company is at least honest about it (after all, the bar is low ) and don’t wait for users to go through the annoyingly tiring updating process and then report the issues. Hopefully the solutions will come through OEMs or next month’s cumulative update.

As always, we recommend waiting a few months before moving on to a new version of the operating system. For those who want to have 100% confidence in a new version, it is better to stick to the latest released version (November 2019 update in this case) rather than the latest version. But if you are a fan of Windows 10, you can choose to install Windows 10 version 2004 manually. Again, Microsoft recommended that you don’t if the above list of known issues affects your device.

* solved by June 9 cumulative update.
** up to and including June PT update; resolved by the June 18 out-of-band update.
*** resolved through July 14 cumulative update.
**** resolved through July 31 KB4568831 (currently in preview)
