I had a clean install of build 14393.0 and wanted to update to 14393.222 via a cumulative update KB3194496 But this is a REALLY dangerous update to do via windows update. So when I became aware of this I hesitated to do the update the normal way. What I describe below is an offline method to update which is much safer to do. Often microsoft provide an easy way to do this for some updates, but sadly haven't done so for this one. The first rule for any update is READ. Read as much as you can to ascertain any potential dangers lurking within such updates. If there are such problems the internet is probably awash with scathing comments. And so it is with KB3194496. Just google it and you will be bombarded with complaints about it. And do this before trying to update. Of all criticisms I think the most pertinent one is that this build was originally released to Windows Insiders and microsoft were warned in no uncertain terms that it is BAD…….REALLY BAD!!! Nevertheless microsoft in their infinite wisdom released exactly the same build to the public. Understandably the internet exploded and went nuclear against microsoft. WHY? WHY MICROSOFT? WHY? Despite the disasters associated with this update what is not well known is that there is actually a safe way to install this update. First it is advisable to completely disable windows update, actually. You can turn it back on later if you want to. To do this, just open services by searching for services.msc in Cortana/Search box and open it. Find Windows Update in the services list. Double click Windows Update services. In the Windows Update Properties Window, click stop and select ‘Disabled’ in the Startup type list box. Click Apply and OK. Now we do the update offline. And it is this aspect which is making it a much safer way to update. It is not so much the update itself which is dangerous, but rather the way windows update interacts with it that had resulted in so many disasters. We are actually totally circumventing windows update here thus averting such disasters. Download the .cab file for KB3194496 depending if you have 64 bit or 32 bit: 64 bit: http://download.windowsupdate.com/c..._2cacef6b46462af81dd957d5b883f32665aad56e.cab 32 bit: http://download.windowsupdate.com/d..._f5ab829a5d2fad9d625797df46ab6ea95cfd78e6.cab Move it to C:\update Search for cmd in Cortana/Search box, right click and run as administrator. Now copy this into the command line in cmd: For 64 bit: dism /online /add-package /packagepath:"C:\update\windows10.0-kb3194496-x64_2cacef6b46462af81dd957d5b883f32665aad56e.cab" For 32 bit: dism /online /add-package /packagepath:"C:\update\windows10.0-kb3194496-x86_f5ab829a5d2fad9d625797df46ab6ea95cfd78e6.cab" Because this particular cab file is so large (compared to many other cab files) it is going to take quite a while to run. It may even seem to have stalled. It hasn’t. Just be patient and wait. You will eventually be prompted to restart. Restart and the update will install normally. And with no disasters caused by windows update. You may check the build number has been increased to 14393.222 by using the “winver” tool to find the build number of your Windows 10 system. To launch it, you can tap the Windows key, type “winver” into the Start menu, and press Enter. You could also press Windows Key + R, type “winver” into the Run dialog, and press Enter. And if you are really brave, you may then re-enable windows updates in services.msc and check for more updates the normal way.
