Today is the second Tuesday of the month, which means that it's Patch Tuesday, and Microsoft has released new updates for all supported versions of Windows. As usual, all four versions of Windows 10 got new builds, but Windows 7 and 8.1 got some love as well.
Windows 7 SP1 hasn't received mainstream support since 2015, but extended support will continue until 2020. Today, users of the OS are receiving KB4034664, which can be downloaded and installed manually here. It contains the following fixes:
Security updates to 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.
There's also a security-only update, KB4034679, which can be downloaded here. It contains a similar changelog to the Monthly Rollup, being that KB4034664 only contains security fixes. Both updates also apply to Windows Server 2008 R2 SP1.
Windows 8.1 and Server 2012 R2 users got KB4034681, which can be downloaded here. Here's what got fixed:
Addressed issue where a LUN connection that was received after the buffer allocation during iSCSI statistic collection overflowed the buffer and caused error 0x19. A UI issue that hides the iSCSI targets will be addressed in an upcoming release.
Security updates to 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.
The security-only update, KB4034672, offers the same release notes, but you can grab that here.
As always, you can get today's Monthly Rollups through Windows Update in the Control Panel, or you can download and install them manually via the links provided.
