[German]Microsoft has updates the list of 'known issues' for Windows 10 May 2019 Update (Version 1903). Some bugs has been mentioned since May 2019. But there is also good news, because some problems can now be fixed or have been corrected by updates. Here is a rough overview of what has changed.
When upgrading a Windows 10 system to the new version 1903 (May 2019 Update) there may be several issues. Microsoft has set upgrade stopper for several known issues. I had already reported about such problems in a series of articles (see Windows 10 V1903: Known Issues – Part 1). Similar to Windows 10 V1809, Microsoft has published a list of Known Issues for the Windows 10 May 2019 Update (Version 1903). This list is available here.
Intermittent loss of Wi-Fi connectivity
Some older computers may lose Wi-Fi connectivity due to an outdated Qualcomm driver. A remedy is an updated Wi-Fi driver from the device manufacturer (OEM), if available and if this driver works. Microsoft has therefore blocked the feature update to Windows 10 version 1903 for these machines with an older Windows 10. To upgrade these machines to version 1903, an updated Wi-Fi driver from the device manufacturer (OEM) must first be installed.
Microsoft does not recommend users of these systems to attempt an upgrade via the Windows Update page and the Update Now button (if the blockage does not occur). It is also not recommended to use the Windows Media Creation Tool to create an installation media and then try an upgrade with the old driver.
This was already mentioned in May 2019 (see this article – part 2). However, Microsoft updated the status page entry on August 1, 2019, as updated drivers from Qualcomm are now apparently being distributed to OEMs.
The German comment here I notice that users with Ralink/Mediatek and Realtek network cards also have issues with the WLAN connection. And in this comment someone mentions an Intel AC 8265 device with issues.
Gamma ramps, color profiles, and night light settings
The problems with gamma ramps, colour profiles and night light mode are still unsolved. Microsoft writes that some scenarios have been identified in which gamma ramps, color profiles and night light settings no longer work. Redmond gives the following scenarios where problems can occur:
- Connecting to (or disconnecting from) an external monitor, dock, or projector
- Rotating the screen
- Updating display drivers or making other display mode changes
- Closing full screen applications
- Applying custom color profiles
- Running applications that rely on custom gamma ramps
This applies to Windows 10 V1903 client. If the night light mode no longer works, Microsoft suggests a restart. These bugs were also mentioned in part 2 of my article series. Microsoft has been working since May 2019 (unsuccessfully) to fix these problems. At the moment, a manual upgrade to Windows 10 V1903 is not recommended – but an upgrade stop has not been set.
But there are fixed issues too
Microsoft was able to resolve some issues reported since May 2019. Microsoft lists the fixed bugs on this status page.
Fixed screen brightness control
The first fix concerns the problem that the brightness of the screen display could not be adjusted or changed. Microsoft and Intel had identified a problem with driver compatibility on devices configured with certain Intel display drivers. After upgrading to Windows 10, version 1903, the system allowed the brightness settings to be adjusted. But the actual screen brightness does not change.
As a precaution, Microsoft had blocked the upgrade to Windows 10 Version 1903 and recommended not to upgrade manually until the problem was resolved. The issue was fixed with the July 2019 update KB4505903 (see also Windows 10 V1903 Update KB4505903 (07/26/2019)). Just for the the records: Microsoft lists a bunch of known issues with this update. Not every user will be able to install this update.
Fixed blank screen issue with Microsoft Store
Furthermore, Microsoft states on this Messages page that the issue 'Microsoft Store users can see an empty window when clicking certain buttons' has been fixed since August 1, 2019. The company writes about it:
Some customers running the version of the Microsoft Store app released on July 29, 2019 encountered a blank screen when selecting "Switch out of S mode," "Get Genuine," or some "Upgrade to [version]" OS upgrade options. This issue has now been resolved and a new version of the Microsoft Store app has been released. Users who encountered this issue will need to update the Microsoft Store app on their device. If you are still encountering an issue, please see Fix problems with apps from Microsoft Store.
