Microsoft recently released the May 2019 Patch Tuesday updates adding a series of fixes and improvement to all the Windows 10 versions currently supported.

The tech giant rolled out two new updates to Windows 7 users: KB4499175 and KB4499164, respectively. Security update KB4499164 fixed some of the issues introduced by KB4493453 last month.

On the other hand, KB4499175 includes some quality enhancements for Windows 7 SP1 and Windows Server 2008 R2 SP1 users. 

Microsoft has a bad history when it comes to new updates. A better approach is to back up your system before installing the latest updates on your PC — just in case something goes wrong.

KB4499175/KB4499164 changelog

App authentication issues fixed

Some Windows 7 users reported that they were experiencing authentication issues for apps that relied on unconstrained delegation.

The authentication issues occur on the expiration of Kerberos ticket-granting ticket. The latest cumulative updates for Windows 7, KB4499175 and KB4499164, addressed this issue.

Security updates for  Microsoft products

KB4499175 and KB4499164 brought important security updates for various applications including Microsoft Graphics Component, Windows Cryptography, Windows App Platform and Frameworks, Microsoft JET Database, Windows Kernel, Windows Server, Windows Wireless Networking, and Windows Storage and Filesystems.

MS Excel formatting issues

Some Japanese fonts such as MS PGothic or MS UI Gothic caused a change in cell size, layout, or text. Update KB4499164 fixed this issue.

KB4499164 known bugs

Luckily, Microsoft didn’t report any known issues in KB4499175. However, just one issue came along with KB4499164. Microsoft collaborated with McAfee to identify the root-cause of the bugs affecting systems that are running any of the following solutions:

  • McAfee Host Intrusion Prevention (Host IPS) 8.0
  • McAfee Endpoint Security (ENS) Threat Prevention 10.x
  • McAfee VirusScan Enterprise (VSE) 8.8

The company says that your computer may either become slow or experience a slow startup after the installation of KB4499164. Microsoft is currently working on a fix to solve this problem.
