Few weeks back I have decided to stop receiving the insider builds for Windows 10 as I hardly found anything interesting that needs such huge volumes of downloads and my precious time! (A bit prudish here). Well it was all easy…not entirely. Even after leaving the Insider program for this particular PC, I kept watching the Windows Update program trying to download the subsequent builds and miserably failing to install them. Fortunately for me, this PC is mostly used as a media center, hooked to my TV.
To stop receiving the newer builds, I unlinked my Live account finally and deleted the C:\Windows\SoftwareDistribution folder after disabling Windows Update for a short period.
Then I realized that I had this issue with a cumulative update KB3194496! Each time I tried update, the lengthy process will fail with “we couldn’t complete the updates, undoing changes.”
After few days search, I came across this link through “Bing”, the greatest search engine EVAR invented by a man!
Though there were many other POSTs explaining some different types of fixes, I opted to go with the solution provided by Microsoft, running a small .msi file downloaded from this link
I had a reason for choosing this fix, as I “was” an Insider while the patch was downloaded and failed the first time. Whatever, after running the .msi and answer with “A” to the prompt in the command line, I downloaded and installed the update without any issues. You may try the same, if you are/were an Insider!
