Download KB4509479 and update KB4509478

Last night Microsoft announced two more Windows 10 updates. These are the updates

  • KB4509479 for Windows 10 version 1809 on build 17763.593 and
  • KB4509478  for Windows 10 version 1803 on build 17134.860.

Both updates have been available for download since last night via Windows Update and the Windows Update Catalog . At the end of this article, we also listed the latest download links that you can use to download the Windows 10 updates directly.

The following changes are included in update KB4509479 and update KB4509478   :

  • These two updates resolve an issue that could prevent devices from connecting to some Storage Area Network (SAN) devices after installing KB4497934 through the Internet Small Computer System Interface (iSCSI). An error message with the description “Target could not respond to a login request in good time” may also be displayed in the System log section of the event viewer with event ID 43 from iScsiPrt.

However, a few bugs in these two updates are also known. These are expressed as follows:

Problem 1:

Certain operations, e.g. For example, renaming files or folders on a shared cluster volume (CSV) may fail with the ” STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5) ” error . This occurs when you perform the operation on a CSV owner node through a process that does not have administrator privileges.

Workaround:

Perform the process from a process that has administrator privileges.

Microsoft is already working on a solution and will provide an update in an upcoming version.

Problem 2:

After installing KB4493509 , devices with some Asian language packs installed may receive the error ” 0x800f0982 – PSFX_E_MATCHING_COMPONENT_NOT_FOUND “.

Workaround:

  • Uninstall and then reinstall any recently added language packs. For instructions, see Manage input and display language settings in Windows 10.
  • Select Check for updates and install the April 2019 cumulative update. For instructions, see Update Windows 10.

Note: If reinstalling the language pack doesn’t solve the problem, reset your PC as follows:

  • Go to Settings app> Recovery.
  • Select ” First Steps ” under the option ” Reset this PC “.
  • Select Keep my files.

Here, too, Microsoft is already working on a solution and will provide an update in an upcoming version.

Problem 3:

We are investigating reports that a small number of devices may display a black screen when they first log in after installing updates.

Workaround:

To fix this problem, press Ctrl + Alt + Del , then select the power button in the lower right corner of the screen and click Restart. Your device should now restart normally.

This problem will also be solved with one of the next cumulative Windows updates.
