Windows 7/8.1 Preview Rollups Oktober 2017

[English]Am 17. Oktober 2017 hat Microsoft die Monthly Preview Rollups KB4041686 für Windows 7 und KB4041685 für Windows 8.1 (sowie die Server Pendants) freigegeben. Hier ein paar Informationen zu diesen Updates.

Update KB4041686 für Windows 7

Update KB4041686 (Preview of Monthly Rollup für Windows 7 SP1 und Windows Server 2008 R2 SP1) enthält Verbesserungen und Fixes aus dem monatlichen Rollup KB4041681 vom 10. Oktober 2017 sowie folgende 'Qualitätsverbesserungen':

• Addressed issue with the Universal CRT where _stat32i64() returns an incorrect drive number (error 0xFFFFFFFF) when using a relative path.
• Addressed issue in the Universal CRT where incorrect characters were returned when the tolower() function was called.
• Addressed issue where the Universal CRT _splitpath() function was not handling multibyte strings correctly, which caused apps to fail when accessing multibyte filenames.
• Addressed issue where the Universal CRT caused linker (link.exe) to stop working for large projects.
• Addressed issue where USBHUB.SYS randomly causes memory corruption that results in random system crashes that are extremely difficult to diagnose.

Das Preview Rollup Update hat leider zwei unschöne Bugs, die Microsoft folgendermaßen beschreibt:

• After installing KB4041686, package users may see an error dialog that indicates that an application exception has occurred when closing some applications. This can affect applications that use mshtml.dll to load web content. The failure only occurs when a process is already shutting down and doesn't impact application functionality.
• Installing this update may cause applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) to fail when creating or opening Microsoft Excel .xls files. The error message is, "Unexpected error from external database driver (1). (Microsoft JET Database Engine)".

An beiden Problemen arbeitet Microsoft und will einen Fix in den kommenden Releases bereitstellen. Für den Microsoft JET Database Engine-Fehler schlägt Microsoft vor, die Microsoft Access Database Engine 2010 Redistributable herunterzuladen und zu installieren. Dann ist der DB-Connection-String Microsoft Excel so anzupassen, dass der ACE-Provider genutzt wird. Der String Provider=Microsoft.Jet.OLEDB.4.0 ist zu Provider=Microsoft.ACE.OLEDB.12.0 zu ändern.

Da das Update als optional klassifiziert wurde, empfehle ich, auf das Update zu verzichten.

Update KB4041685 für Windows 8.1

Update KB4041685 (Preview of Monthly Rollup for Windows 8.1 and Windows Server 2012 R2) enthält Verbesserungen und Fixes aus dem monatlichen Rollup KB4041693 vom 10. Oktober 2017 sowie folgende Verbesserungen:

• Addressed memory leak issue in combase that occurs while converting Rich Text to Unicode.
• Addressed issue in which using smart card authentication to connect RDP to the Windows 2012 RDS server fails intermittently. The issue is related to a timing problem in the LogonUI process. It is most common when clients use virtual smart cards.
• Addressed issue that affects the Universal CRT in which _stat32i64() returns an incorrect drive number (error 0xFFFFFFFF) when using a relative path.
• Addressed issue in the Universal CRT in which incorrect characters were returned when the tolower() function was called.
• Addressed issue in which the Universal CRT _splitpath() function was not handling multibyte strings correctly. This caused apps to fail when accessing multibyte filenames.
• Addressed issue in which the Universal CRT caused linker (link.exe) to stop working for large projects.
• Addressed issue in which the MSMQ performance counter (MSMQ Queue) may not populate queue instances when the server hosts a clustered MSMQ role.
• Addressed issue in which AD FS can no longer ignore "prompt=login" during authentication. A "Disabled" option was added to support scenarios in which password authentication is not used. For more information, see AD FS ignores the "prompt=login" parameter during an authentication in Windows Server 2012 R2.
• Addressed issue in AD FS in which MSISCookies in request headers could eventually overflow the headers size limit. This caused a failure to authenticate and return HTTP status code 400: "Bad Request – Header Too Long."
• Addressed issue in which adding user rights to an RMS template caused the Active Directory RMS management console (mmc.exe) to stop working and return an unexpected exception.
• Addressed issue in which USBHUB.SYS randomly caused memory corruption that caused random system crashes that are extremely difficult to diagnose.

Auch bei diesem Update treten die beim Windows 7-Update beschriebenen zwei Bugs auf. Als weiterer Bug gibt Microsoft an, dass der Internet Explorer Startprobleme hat, wenn die Textgröße für Symbole per Systemsteuerung (Anzeigeeinstellungen) auf einen höheren Wert gesetzt wurde. Als Workaround gibt Microsoft an, die Textgröße für Icons auf einen kleineren Wert zu setzen. Microsoft arbeitet an der Beseitigung der Bugs. Da das Update optional ist, würde ich dieses nicht installieren.
