Key Improvements and Fixes

Only fixes that come with this release will get applied to your System, surpassing any fix that comes in the previous patch-up update. The key changes are –

  1. Earlier, when users try to use multiple audio devices on applications that support this feature by providing advanced options ultimately leads to devices to stop responding. Some apps which face this bug were Realtek HD Audio Manager, Windows Media Player, and Sound Blaster Control Panel. They have fixed this issue now, thus allowing users to select an audio output device different from the default one.
  2. They bring a fix for Game Mode that will provide a smooth interface to record or stream top games.
  3. The Company now allows the activation of Windows 10 Enterprise Insider builds for Microsoft Azure’s virtual Desktops.
  4. Earlier, when users update their operating system, this leads to the loss of the Reading list and Favorites section on Microsoft Edge. They have solved this trouble too with this release.

Known Issues- Cumulative Update KB4490481


When you install this release, certain apps will stop working due to MSXML6. This occurs as there is an exception thrown during node operations like- insertBefore(), appendChild() and moveNode().

If you go to edit a group policy object that contains policy preferences for IE 10, the Group Policy Editor may stop as well.

They are working on a resolution and the same will appear by the next cumulative update.
In case, you edit per font-end user-defined characters i.e. EUDC, it may bring BSOD at startup or Screen stops responding. This is not a common setting among people who belong to Asian-region.In simple, disable the per font EUDC feature on your PC. You can edit the registry too to solve this bug. Have a look at here, for more details.

If you use IE 11 or some other apps which use WININET.DLL, don’t go for this patch-up update, otherwise, you may face authentication issues.

By default, it occurs only when two users use the same account to open more than one login session or the same Windows Server Machine/ Remote Desktop Protocol. Some users have noticed the following symptoms-

  1. Cache size and location display ‘0’ or empty
  2. Keyboard shortcuts might not work properly
  3. Webpages may fail in between to load or render correctly
  4. Credential prompts issues
  5. Downloading files trouble

If you do face such issues, try to create unique user accounts. This will ensure that people won’t share the same user account while logging to a WSM. You can disable multiple RDP sessions too for a single user account to solve this trouble.

Microsoft will soon provide a solution to this in its upcoming release.
