The fastest way to patch a Windows 7/Server 2008 R2 machine is to take advantage of the Convenience Update Rollup from April 2016 (KB3125574). The Conv. UR updates a lot of components and to ensure that that happens without any servicing problems, it has as a prerequisite the Servicing Stack Update from April 2015 (KB3020369). To install most of the other patches in between April 2016 and October 2016 we will include the following updates:

KB3020369 (April 2015 Servicing Stack Update)
KB3125574 (April 2016 Convenience Update Rollup)
KB3177467 (September 2016 SSU)
KB3172605 (July 2016 Functional Update Rollup, 7C* package)
KB3179573 (August 2016 FUR, 8C* package)
KB2841134 (Internet Explorer 11, Optional)
KB3185330 (October 2016 Monthly Quality Rollup, 10B' package [contains September 2016 FUR, 9C* package])

*3rd Tuesday package of that month.

Download all the packages from the Microsoft Update Catalog (now updated to work on all browsers) to a folder:

Expand the .MSU files to extract the .CAB file which will be used with DISM:



Command used:
expand -f:*Windows*.cab C:\files\Window7MediaRefresh\*.msu C:\files\Window7MediaRefresh\CABs (thank you abbodi1406)

Afterwards we should have the following:



For this guide we will use the install.wim file from a Windows 7 Enterprise x64 SP1 Media:



Mount the image as described in the offline servicing article below:

Add or Remove Packages Offline Using DISM
https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-8.1-and-8/hh824838(v=win.10)

Dism /Mount-Image /ImageFile:C:\test\images\install.wim /Name:"Windows 7 ENTERPRISE" /MountDir:C:\test\offline

And now we can start adding the first package, the KB3020369 SSU:

Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\files\Window7MediaRefresh\CABs\Windows6.1-KB3020369-x64.cab



We can check the installation state using the command below:
Dism /Image:C:\test\offline /Get-Packages

It is in a "Install Pending" state:
Package Identity : Package_for_KB3020369~31bf3856ad364e35~amd64~~6.1.1.1
State : Install Pending
Release Type : Update
Install Time : 11/4/2016 9:11 AM

The next update to install is the Convenience Update Rollup KB3125574:

Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\files\Window7MediaRefresh\CABs\Windows6.1-KB3125574-v4-x64.cab



Package Identity : Package_for_KB3125574~31bf3856ad364e35~amd64~~6.1.4.4
State : Install Pending
Release Type : Update
Install Time : 11/4/2016 10:33 AM

We cannot continue to install updates offline, because of the DISM limitation below:

Limitations
When you are installing a package in an offline image, the package state is “install pending” because of pending online actions. In other words, the package will be installed when the image is booted and the online actions are processed. If subsequent actions are requested, they cannot be processed until the previous pending online action is completed. You can use the /PreventPending option when you add a package with /AddPackage to skip the installation of a package when there are pending online actions.
https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-8.1-and-8/hh825265(v%3dwin.10)#limitations

Commit the changes with the command below to seal the image:
Dism /Unmount-Image /MountDir:C:\test\offline /Commit



Now we need to install a Windows 7 VM/PC with this image to finish the outstanding servicing actions and install the other updates. Do this either by hand or using your favorite deployment tool.

After the image is installed we should see the following (SP1 + KB3020369 + KB3125574 only):

C:\Windows\system32>Dism /Online /Get-Packages

Deployment Image Servicing and Management tool
Version: 6.1.7600.16385

State : Installed
Release Type : Update
Install Time : 11/21/2010 3:01 AM

Continue to install updates 3-5 using the DISM commands below:

Dism /Online /Add-Package /PackagePath:C:\temp\Windows6.1-KB3177467-x64.cab



Dism /Online /Add-Package /PackagePath:C:\temp\Windows6.1-KB3172605-x64.cab



Dism /Online /Add-Package /PackagePath:C:\temp\Windows6.1-KB3179573-x64.cab




Step 6, which is installing IE11, is optional, in case you have business critical applications that are dependent on an older Internet Explorer version. The security-only, monthly rollup, and preview rollup will not install or upgrade to these versions of Internet Explorer if they are not already present, so we will install IE11 next, before we apply the monthly rollup.

This will be the IE version installed, if we do not upgrade it:



The last update to install is KB3185330, at the moment of writing this guide, in the future just replace it with the latest monthly/preview rollup, found on the page below:

Windows 7 SP1 and Windows Server 2008 R2 SP1 update history
https://support.microsoft.com/en-us/help/22801/windows-7-and-windows-server-2008-r2-update-history

Dism /Online /Add-Package /PackagePath:C:\temp\Windows6.1-KB3185330-x64.cab



Now we can search online for the remainder of the updates or just capture the image after generalizing it, if we want to finish as fast as possible.

Online search results after the above updates (34/39 optional updates are language packs):

Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\files\Window7MediaRefresh\CABs\Windows6.1-KB3125574-v4-x64.cab

Unmount and commit the changes to the install.wim file:
Dism /Unmount-Image /MountDir:C:\test\offline /Commit

Install a reference machine with the above install.wim file and continue to install the updates:
