I haveupgrade Windows 8.1 Pro 64bit (English US) to Windows 10 Pro, 64bit also English(US) when I received the Microsoft notification in my HP ENVY 17 laptop, onJuly 29th according to my memory.
The upgradingprocess was without difficulties, like a charm; the laptop continued to worksatisfactorily and I am happy with Windows 10
Since thattime a number of updates were automatically downloaded and installed forWindows, Windows Defender (a lot), Office and two Cumulative Updates: KB3105213and KB3116869.
The laptophas i7, RAM 16GB, HDD 1TB with 750GB of free space.
However inNovember v1511, Build 10586 was not automatically downloaded and obviously notinstalled. So, my current version still is 10.0 Build 10240.
Therefore,I tried to install 10586 manually with an ISO file saved on a DVD and downloadedvia the Media Creation Tool and Tech Bench.
Aftermounting the ISO I tried to install 10586 opening its exe file as Administratorbut installation always stuck at 25%. Similarly with the program downloaded to anUSB and opened via Advanced startup or directly from the USB itself.
As anexternal device I only have an USB Microsoft mouse. I also tried to use the laptoptrackpad instead the mouse but results were the same.
At 25%always appear the same phrase: “Something happened Windows 10 installation has failed”.
Ialso tried to deactivate both Windows Firewall and Windows Defender, but sameresult.
Both sfc /scannowand dism /online /cleanup-image /restorehealth commands were and are OK.
I willappreciate your advice and instructions in order to finally install 10586.
