Microsoft has made a massive new Windows 10 upgrade available to users around the world. Unfortunately, the company has also confirmed it is full of problems.

In its official release information for Windows 10 v2004 (also known as the ‘May 2020 Update’), Microsoft has listed 10 significant “Known Issues” which are currently active. These include problems with Bluetooth, audio, gaming, connectivity, graphics card drivers and system stability.

05/29 Update: picked up by Windows Latest, Microsoft has confirmed additional problems with Windows 10. In a new blog post, the company states that Windows 10 PCs which take advantage of the Fast Start feature (automatically enabled on many modern PCs - here's a manual How To guide) may not install updates when they are shut down. Instead, users will have to restart their computers for updates to be applied. Microsoft has not put a timeline on a fix for this feature and users concerned about the buggy spate of Windows 10 updates recently may not be too unhappy that they are not installed, but the company has promised "to address this in a future Windows version."

Among these, the most high profile are incompatibilities with certain Nvidia display drivers (details), Conexant and Synaptics audio drivers (details), broken mouse control (details), plugging and unplugging Thunderbolt docks (details), broken variable refresh rates with Intel graphics (details), difficulty connecting to more than one Bluetooth device (details) and unexpected restarts with certain network adapters (details).

Furthermore, while the May 2020 update does bring some welcome security upgrades, there are some concerns here as well.

To its credit, Microsoft has taken two proactive steps. First, it is applying an algorithm which attempts to establish whether your PC will upgrade reliably before starting the update. Second, it is currently only rolling out the May 2020 update to users who “Check for Updates” - although that is admittedly a sizeable number.

Ultimately, the pros will outweigh the cons in Windows 10 v2004 (there is a lot of good stuff) but there are a number of road bumps to be overcome and I would advise mainstream Windows 10 users stay away from it for the time being. May has been a difficult month for Microsoft with the endless list of problems caused by KB4556799 and it has been in firefighting mode.

The Windows 10 May 2020 Update is on its way. We’re offering this update to compatible devices, but your device isn’t quite ready for it. Once your device is ready, you’ll see the update available on this page. There’s nothing you need to do at this time.

I've made a disk image of the current system and so will go for the new W.10 version when its available. I like to see what updates are all about.

I still have Windows 7.

me too, tiff.
