Windows 10/11 June Update Known Issues

Microsoft warns about Windows 10/11 June update because a lot of the problems encountered by users who upgrade early on are still being investigated by the team. Although a lot of the issues have been resolved already, there is still a long list of issues that they need to work on.

Active Issues

Here is a summary of issues that the Microsoft team is currently trying to fix:

Print spooler error

After installing KB4557957, some printers may be affected and be unable to print. Users might encounter a print spooler error which halts the printing process. The print spooler might also close suddenly when attempting to print, causing no output from the affected printer. Users might also encounter problems with the apps used to print from, such as email or messenger apps. You might get an error notification from the app or it might crash unexpectedly. This error affects most Windows 10/11 and Windows Server versions.

DISM error

When you use the Deployment Image Servicing and Management or DISM utility to check for corruption, you might get a report stating that corruption is still present even after repair. Usually, the /restorehealth command (DISM.exe /Online /Cleanup-image /Restorehealth) should be able to detect and correct system corruption. But if you installed the latest update, DISM might report that there are still corrupted files even though they have been fixed already. Windows has not yet fixed this issue but suggested a workaround instead. If you’re getting false DISM reports, you can verify the true state of corruption by running the DISM.exe /Online /Cleanup-Image /ScanHealth command.

Variable refresh rate not working

Windows 10 version 2004 users who use an Intel integrated graphics processing unit (iGPU) display adapter and are using a monitor with Variable refresh rate (VRR) are very likely to encounter incompatibility issues. Turning on VRR on the affected computer will not enable the VRR for games that are using Direct X 9. Microsoft and Intel are still working on a fix and warns Windows users not to upgrade.

Most of these errors are still being fixed and Microsoft did not release a timeframe for when the patches will be released. For the meantime, Microsoft advises Windows users with firmware or driver issues to hold off from installing the latest update.

Resolved Issues

Although the Windows 10/11 June update may be full of problems, Microsoft is currently working on resolutions to address these issues. In fact, it has resolved some of the bugs related to the latest feature update, including:

Always On, Always Connected errors

Devices using Always On, Always Connected feature might encounter compatibility issues with Windows 10 version 2004. The affected devices will see multiple Always On, Always Connected capable network adapters, including the Microsoft Surface Pro 7 and Microsoft Surface Laptop 3.

Some Windows users reported an incompatibility problem between apps and games using GameInput Redistributable and Windows 10 version 2004. The affected apps or games did not have any mouse input. However, Microsoft’s investigation revealed that the issue is not at all related to any version of GameInput Redistributable installed in the device. The problem could be isolated or related to some other factors. Hence, the safeguard hold has been removed.

Microsoft is now accelerating the roll out of the May/June 2020 update or Windows 10 version 2004, despite the many errors that remain unfixed. However, Microsoft is proactively blocking some affected devices from upgrading and has even issued Windows 10/11 June update warnings to alert users about these existing problems.

Windows 10/11 June Update Features

It is not all bad news for the latest Windows 10/11 feature update. The new update includes a lot of changes including:

  • Cortana’s upgrade to become a personal productivity assistant. This virtual assistant is now able to help you use. In the latest Windows version, Cortana is now undocked from the taskbar, enabling you to move or resize it like any other app. You can use the virtual assistant to open apps, such as Microsoft 365 apps, and adjust settings like brightness. It also has an improved email feature that allows you to create emails and a new calendar feature you can use to create calendar entries and ask about meetings.
  • Search Home additions. This new feature update adds four quick searches to your Search Home, namely weather, top news, today in history, and new movies. This makes quick searches, well, a lot quicker.
  • New Kaomoji or Japanese emoticons. The emoji keyboard shortcut includes new Kaomoji characters, along with other emojis.

With the version 2004, the Reset This PC feature now has an option to download the setup files from the cloud (or from the internet) instead of using the local installation files.
