Windows Update error 0x80073712

I was not able to install Windows 8.1 Update for x64-based Systems (KB2919355), For a last few months. It's not like I was trying to do it everyday, simply when I noticed that I am not able to install it I tried again after few weeks. Unfortunately this update is required for me to install other update that is required to play with new .NET 4.6 preview framework (link to Visual Studio 2015 download, because that's the place that allowed framework to be downloaded).

What didn't work

Using File System Checker to repair missing or corrupted system files

sfc /scannow

Running in cmd as Admin following commands

net stop wuauserv
net stop bits
net stop cryptsvc
ren %systemroot%\System32\Catroot2 Catroot2.old
net start cryptsvc
ren %systemroot%\SoftwareDistribution SoftwareDistribution.old
regsvr32 wuapi.dll
regsvr32 wuaueng.dll
regsvr32 wucltux.dll
regsvr32 wups2.dll
regsvr32 wups.dll
regsvr32 wuwebv.dll
net start bits
net start wuauserv
net start Eventlog

What resolved the problem

Running in cmd as Admin following commands

DISM.exe /Online /Cleanup-image /Scanhealth

DISM.exe /Online /Cleanup-image /Restorehealth
DISM process failed few times when I run it.

Run psake task from powershel

I constantly keep forgeting this command, because I use it once per few months. Here is how to trigger a psake task from pshell:
.\psake.ps1 "<fileWithTasks.ps1>" "<taskName>"

Some example:
.\psake.ps1 "default.ps1" "UpdateDatabase"
