1 min read

This month’s patch Tuesday event is not only Windows 10 received a cumulative update, and Windows 7 / 8.1 also received a security update. Windows 7 SP1 no longer receives mainstream support in 2015, but extended support will continue through 2020. Users who still use the system today are now updated with KB4034664 and can also be downloaded manually via this link.


The KB4034664 update mainly includes security updates for the Microsoft JET Database Engine, Common Log File System Driver, Microsoft Windows Search Component, Volume Manager Driver, Internet Explorer, Windows Server, and Windows Kernel-mode drivers.

In addition, there is a security update KB4034679, the user can use this link to manually download. The update log is somewhat similar to Monthly Rollup, but KB4034664 contains only security updates. The two updates also apply to Windows Server 2008 R2 SP1.

Windows 8.1 and Server 2012 R2 users have updated KB4034681, where users can download manually . Major fixes include

● Fix the buffer allocation in the case of iSCSI statistics collection overflows to accept LUN connections and cause error 0x19 issues. The user interface will hide the iSCSI target in future version updates.

● Security updates for Windows Server, Microsoft Windows Search Component, Internet Explorer, Volume Manager Driver, Common Log File System Driver, Microsoft Windows PDF Library, Microsoft JET Database Engine, Windows Kernel-mode drivers, and Windows Hyper-V.

Only the security update KB4034672 provides the same update log that the user can get through here.
