Windows 10 upgrade key fails repeatedly

Question

 Why am I continuing to have Win7 Serial Number Key problems upgrading to Windows 10 64-bit, despite my install attempts using USB, DVD, and website software downloaded from Microsoft?  I have repeatedly attempted to upgrade our HP DV6  (2 years old) to the Windows 10 Upgrade with no success and a lot of frustration...  The problem seems to be the HP Win7 install key placed on our laptop by HP is not recognized by either the Win10 upgrade DVD, the Win10 upgrade USB Memory Stick or the Microsoft Win10 install website.  The DVD and USB install attempts say the HP serial number originally installed on our laptop by HP is not recognized and prevents the upgrade from continuing.  The Win10 website upgrade application starts, tries to load temporary files, and then abruptly terminates during the install attempt with no diagnostic or error message. Microsoft Tech Support (Level 3) verified about 1 week ago the DV6 laptop is fully up-to-date on all drivers,  Windows 7 software, and fully ready for the Win10 upgrade.  The laptop currently has a fully working wireless connection to the Internet.  All Anti-Virus and Anti-Malware software has been fully disabled to allow the upgrade attempts. The HP Software Advisor website says all HP software and drivers are up-to-date.  All TMP files etc. have been cleaned out with CCleaner.  The primary HD has been fully defragmented.  The laptop has 6MB of memory, 500+ GB available disk space on the primary partition, and 150MB available on the System partition.  The laptop has recently been been upgraded to use Internet Explorer 11 which is working correctly. Question 1: Why are we continuing to have problems with the HP Win7 Install Key# not being recognized for the Win10 upgrade? Question 2:  is HP trying to regulate when HP owners upgrade their computers to Win10 by controlling when HP Win7 install keys are recognized for Win10 upgrades?  If so, they should inform HP Owners in advance and not through frustrating Owners by trial-and-error.

Answer 1

I finally got the Win10 upgrade to start after a call to Microsoft Tech Support and here's why upgrade problems occurred and how to address them... The problems I experienced are caused by Microsoft and HP who have not made clear when HP laptops that are out of warranty will be allowed to complete the Win10 upgrade o0n the Internet nor how a local Win10 upgrade should be completed.. 1.) I called HP Tech Support about Win10 upgrade problems with abrupt disconnects & they refused to even discuss my concerns unless I bought an *expensive subscription package*. They said my laptop is just out of warranty and the 3rd party contractor company wanted $150 for a 6 month tech support subscription before they would answer any of my basic questions. 2.) Creating a DVD or USB as the startup drive from the Win10 Upgrade ISO downloaded from Microsoft DOES NOT WORK because this causes the bootable software to think it is a new install and not an upgrade. I also could not get the bootable USB stick with the Win10 Upgrade to read correctly and the Setup app crashed with no error message. 3.) Apparently the Microsoft Win10 website is delaying OEM "out of warranty" Win10 upgrades to enable Retail Version Customers, Businesses, and OEM "In Warranty" computers to have the first chance to upgrade. Here's how I solved the Win10 Upgrade problem... In summary, I a.) used MSCONFIG.EXE to disable ALL non-Microsoft Apps (except HP) from loading at startup NOTE: I tried to let all HP hardware & software load, but disabled McAfee Anti-Virus, Spybot S&D, etc. b.) created a permanent virtual drive for only the Win10 Upgrade ISO (I used the *64-bit version* of MagicDisc freeware downloaded from the Internet) c.) booted from the Win7 C: drive, opened the ISO virtual drive, and ran the ISO Setup.exe. d.) the Win10 upgrade Setup.exe ran with no problems, checked for the Internet for updates, and prepared the laptop for the Upgrade. I was then prompted to close the Finished Window, I manually restarted the laptop from the Start Menu and after the POST, the actual Win10 Upgrade started without my having to do anything. e.) As the Win10 Upgrade moved forward, a small message appeared that said my computer may have to be rebooted several times during the upgrade to assure that the correct sets of drivers were detected, loaded, and upgraded. After the Upgrade completes, I will have to re-activate and test the 3rd party Software apps disabled by MSCONFIG individually so I can be sure the drivers and software work correctly. Apps should be reactivated one-at a-time to discover which apps are not compatible with Win10 and/or may require an OEM upgrade. This may require rebooting and testing the 3rd party app one at a time to determine compatibility issues... Please note: Microsoft now tracks everywhere you go on the Internet with Win10 and disabled privacy settings during the upgrade. .
