Updates KB4501226, KB4499177 and KB4489486 (May 2019)

[German]Microsoft has released the two updates KB4501226 for Windows 7 to Windows 8.1 including the server counterparts and KB4489486 for .NET on May 22, 2019. In addition, KB4499177 for Windows 10 V1607 was released on May 23, 2019. Here is some information about these updates.

German blog reader Torsten mentioned this within this comment (thanks for that). He was offered the updates via WSUS. During the research I came across a Windows 10 update.

Update KB4501226 for Windows 7/8.1 und Server

Update KB4501226 introduces a summer time change for Morocco and the Palestinian Authority. The update is available for the following Windows versions:

• Windows Server 2012 R2
• Windows 8.1
• Windows RT 8.1
• Windows Server 2012
• Windows Server 2008 R2 Service Pack 1 (SP1)
• Windows 7 SP1
• Windows Server 2008 Servicepack 2 (SP2)

The correction is necessary for Morocco because during Ramadan, from 5 May 2019 to 9 June 2019, summer time is reset to normal time. For the territories under Palestinian administration, the start of summer time has been set at 29 March 2019. The update is offered via Windows Update, in WSUS or in the Microsoft Update Catalog.

For Windows 10 and its server counterparts, Microsoft provides the corrections through cumulative updates. These are the updates KB4497934 and KB4499177.

Update KB4499177 for Windows 10 V1607

Cumulative Update KB4499177 for Windows 10 V1607 (Enterprise) and Windows Server 2016 raises the OS Build to 14393.2999 and also includes the time zone correction for Morocco and was released on May 23, 2019. Here is the list of corrections:

• Updates wininet.dll to prevent the re-creation of File Transfer Protocol (FTP) control sessions.
• Addresses an issue that prevents the OS from loading new icon files if it encounters an icon file that has a bad format.
• Addresses an issue to set the date separator properly in the Japanese short date format. For more information, see KB4469068.
• Updates time zone information for Morocco.
• Updates time zone information for the Palestinian Authority.
• Improves performance related to case-insensitive string comparison functions such as _stricmp() in the Universal C Runtime.
• Addresses an issue that may cause a temporary KRB_AP_ERR_MODIFIED Kerberos sign-in failure in applications and services configured to use a Group Managed Service Account (GMSA). This issue occurs after the automatic update of the service account password.
• Addresses an issue that causes a sign-in to fail with the error, "Incorrect Username or password" when using an empty or null password and Windows Defender Credential Guard is enabled.
• Addresses an issue that causes Microsoft Office and other applications to prompt for a password after you change a user account password. This issue occurs on hybrid Azure Active Directory (AD) joined systems.
• Addresses an issue with BranchCache when it is in distributed cache mode. BranchCache may use more disk space than assigned for the republication cache. To fully address the issue, devices that have exceeded the disk space assignments should empty BranchCache using the netsh branchcache flush command.
• Addresses an issue that may cause a Stop D1 error when you increase the random-access memory (RAM) capacity of a CPU ("hot add") on a virtual machine.
• Addresses an issue that may cause event 7600 in the Domain Name System (DNS) server event log to contain an unreadable server name.
• Addresses an issue with apps that have incorrect audits and are not protected by Extranet Smart lockout when they are published using the Active Directory Federation Services (ADFS) RichClient.
• Addresses an issue that fails to record a local user's last logon time even when the user has accessed the server's network share.
• Addresses an issue that may cause error "0x7E" when moving a Network File System (NFS) File Server role and any client is active.
• Addresses an issue with the Windows Management Instrumentation (WMI) class, Win32_PhysicalMemory, which reports 32 GB of memory without a Capacity value.
