Microsoft takes unusual step of listing known issues with Windows May 2020 update

Microsoft has been besieged with Windows 10 update issues of late. Every time they push an update people are waiting to jump on the news immediately listing a tirade of bugs and problems they are having. With the latest May 2020 update, Microsoft has decided to pre-empt that by producing its own list of known issues on its website.

Whether this is because some are system-breakers for some people or they are just trying to control the PR a little better, it’s good that we have an official hit list of problems rather than things popping up all over Reddit and then being syndicated across the news sites.

Some of these issues have a workaround and many may not affect you personally, but it’s certainly worth a good read through to make sure nothing mission-critical is going to change for you, especially as we are all working from home these days and can’t afford the downtime.
