It's been just over two weeks since Patch Tuesday when Microsoft released updates for all supported versions of Windows, but new updates are rolling out today. Today's cumulative updates are for Windows 10 versions 1803, 1709, 1703, and 1607. That makes the only supported version of Windows 10 that's not getting an update is version 1507 on the Long Term Servicing Channel.
If you're like most people, then you're on the Windows 10 April 2018 Update, or version 1803, and you'll see KB4346783. It brings the build number to 17134.254, and you can manually download it here. Here's what got fixed:
Addresses an issue in Microsoft Foundation Class applications that may cause applications to flicker.
Addresses an issue where touch and mouse events were handled differently in Windows Presentation Foundation (WPF) applications that have a transparent overlay window.
Addresses a reliability issue in applications that have extensive window nesting.
Addresses an issue in the Universal CRT that sometimes causes the AMD64 FMOD to return an incorrect result when given very large inputs.
Addresses an issue in the Universal CRT that causes the _get_pgmptr() function to return an empty string.
Addresses an issue in the Universal CRT that causes isprint() to return TRUE for a tab when using the C locale.
Addresses an issue where Microsoft Edge or other UWP applications can't perform client authentication when the private key is stored on a TPM 2.0 device.
Addresses an issue that causes computer certificate enrollment or renewal to fail with an "Access denied" error after installing the April 2018 update. This issue occurs when the registry process has a lower process ID (PID) than all other processes except SYSTEM.
Addresses an issue that, in some cases, failed to clear decrypted data from memory after a CAPI decryption operation was completed.
Addresses an issue that prevented the Device Guard PackageInspector.exe application from including all the files needed for an application to run correctly once the Code Integrity policy was completed.
Addresses an issue where not all network printers are connected after a user signs in. The HKEY_USERS\User\Printers\Connections key shows the correct network printers for the affected user; however, the missing list for network printers from this registry key isn't populated in any app, including Microsoft Notepad, or in Devices and Printers. Printers may disappear or stop functioning.
Addresses an issue that prevents printing on a 64-bit OS when 32-bit applications impersonate other users (typically by calling LogonUser). This issue occurs after installing monthly updates starting with KB4034681, released in August 2017. To resolve the issue for the affected applications, install this update, and then do one of the following:
Use Microsoft Application Compatibility Toolkit to globally enable the Splwow64Compat App Compat Shim
Use the following registry setting, and then restart the 32-bit application:HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print Setting: Splwow64Compat
Type: DWORD
Value1: 1
Addresses an issue that causes the Wi-Fi EAP-TTLS (CHAP) authentication to fail if a user saves credential information before authentication.
Addresses an issue that causes devices that have 802.1x Extensible Authentication Protocol (EAP) enabled to randomly stop working with the stop code ”0xD1 DRIVER_IRQL_NOT_LESS_OR_EQUAL”. The issue occurs when the kernel memory pool becomes corrupted. Crashes will generally occur in nwifi.sys.
Addresses an issue that may remove a Dynamic Host Configuration Protocol (DHCP) option from a reservation after changing the DHCP scope settings.

Addresses a Windows Task Scheduler issue that occurs when setting up an event to start on a specific day of the month. Instead of starting on the specific day of the month you selected, the event starts one week ahead of schedule. For example, if you set an event to start on the third Tuesday of August 2018, instead of starting on 08/21/18, the event starts on 08/14/18.
Addresses an issue that prevents Hypervisor from automatically launching on restart when running a nested or non-nested virtualization scenario after enabling Device Guard.
Addresses an issue that causes the event viewer for Microsoft-Windows-Hyper-V-VMMS-Admin to receive excessive Event ID 12660 “Cannot open handle to Hyper-V storage provider” messages. This issue occurs when performing migration testing on a Windows Server 2016 S2D Cluster Platform. As a result, events are deleted after three hours when the event log size reaches 1 MB.
Addresses an issue that causes virtual functions (VF) to be unintentionally removed when a virtual machine (VM) is saved in Hyper-V Manager. This issue occurs when assigning and loading multiple virtual functions to a single VM during live migration on Windows Server 2016. Saving the VM doesn’t result in a normal shutdown of the virtual functions and doesn’t allow the VF driver to have backchannel communication with the physical function (PF).
Addresses an issue that causes an Azure to on-premise failback operation to fail and puts the virtual machine (VM) into an unresponsive state. This issue occurs if the failback is interrupted by an event such as restarting the Virtual Machine Management Service (VMMS) or restarting the host machine. The failback operation then continues to fail even when the VMMS is running.
Addresses an Active Directory Federation Services (AD FS) issue where Multi-Factor Authentication does not work correctly with mobile devices that use custom culture definitions.

This issue occurs when a custom component binds over Transport Layer Security (TLS) to a Domain Controller using Simple Authentication and Security Layer (SASL) EXTERNAL authentication.
Addresses an issue that generates Event ID 2006 and prevents the Windows Performance counter from reading Server Message Block (SMB) performance counters. This issue occurs when Hot-Plug is enabled for CPUs on Windows 2016 virtual machines.
Addresses an issue that causes users to disconnect from a remote session when the Remote Desktop Gateway service stops working.
Addresses an issue that causes svchost.exe to stop working intermittently. This issue occurs when the SessionEnv service is running, which causes a partial load of the user’s configuration during a Remote Desktop session.
Addresses an issue that may cause the server to be restarted because the system nonpaged pool consumes too much memory.
Addresses an issue that may remove a Dynamic Host Configuration Protocol (DHCP) option from a reservation after changing the DHCP scope settings.
