Windows 10 - Upgrades and version 1511,10586" (aka "Threshold-2")

Since many of us use Windows in our hobby, I thought these notes might be helpful to someone. These tips should work on various computers.

HP21-2010 All-in-One Touch (HP AMD-based quad-core with Radeon-R3 graphics)
- ESC on boot for Post-Menu (BIOS and UEFI Diags)

This is not my main computer but I do use it. While I usually prefer "clean-installs" there is something to be said for easier overlay-installs (if they work). With broadband and more of a cloud focus, I am becoming more trusting of it. However, research of my problem lead to cause being that it was initially upgraded by overlay (aka in-place upgrade) from Windows 8.1.

(8-2014) Came with Windows 8.1. Using Microsoft Account login and email and cloud.
(9-2015) I verified with HP that this model was eligible, so I answered Microsoft's offer and online upgraded (by overlay) to Win-10 from WindowsUpdate soon after its release. No data or pre-installed apps were lost and this computer has been working fine since.
I also installed HP Support Assistant . It's a nice updater for HP drivers and Apps. (It updates itself from it's own separate "About" prompt.)

(1-2016) Threshold-2 Upgrade
Computer has been working fine.
WindowsUpdate tried to "Upgrade to Windows 10 Home. version 1511,10586" (aka "Threshold-2") but Failed Auto-Install several times (as revealed in logs).

Hard-drive Error-check reveals no problems.
For all these procedures, start CommandPrompt as Admin and stay connected to Internet.
Start Version CommandPrompt> ver = 10.0.10240

CommandPrompt> SFC /scannow
- Says it found UN-REPAIRABLE errors

I think options at this point are to try Deployment Image Servicing and Management tool (DISM) or re-install (Overlay or Clean) from full Win10 .ISO (on flash drive)

CommandPrompt> dism.exe /online /cleanup-image /restorehealth
- Says it found UN-REPAIRABLE errors
- HOWEVER, I left PC for a while. Upon return I found that the Auto-Upgrade had started itself again and appeared to be working.
- Win10 (Threshold-2, 1511, 10586) install took about 2 hours (over WiFi) but worked fine. No apps or data-files were erased.

Now Version CommandPrompt says> ver = 10.0.10586
CommandPrompt> SFC /scannow

HP Support Assistant - Installed suggested driver updates - Now Current
WindowsUpdate - Installed suggested software updates - Now Current
- WindowsUpdate History resets and starts-over now (after Threshold-2 update was installed)
Computer working fine with latest version of Windows 10 Home (64bit).

Dell Venue Pro 8345 Tablet (Intel Atom and 32gb SSD ... initially shipped with Windows-8)
- Hold Power & Down-Volume from Power-On to access BIOS.

This machine was also suffering from multiple failed long auto-update (on it's own) Windows-10 upgrade attempts.

The main problems preventing the upgrade were:
1. Lack of "work space" on small SSD/flash memory (about 4gb) . This was compounded by the fact that Dell Backup and Restore (DBaR) was using a good portion (10 gb) of the available space for a Windows-8 Recovery Partition.
2. I installed the recommended (for Win-10 support) BIOS upgrade before attempting it again.
3. Current Win-8 WiFi driver seemed to be having a problem staying connected long enough for the large download installer download. Updated to latest version.

Then, I installed a SD-card in tablet and let Windows use that for Windows-10 Undo Files (these can be deleted later). The upgrade to Windows-10 finally completed successfully.

Dell Backup and Restore (DBaR) can then be uninstalled. It's not supported under Windows-10 anyway ( you now use Microsoft bundled backup tools). After reboot, if DBar's (old Win-8) recovery partition is still there, you can manually remove it. New free space on C: is 14gb.

Nice tablet. Might be a good way to run full Windows MissionPlanner in the field.


  1. I downloaded and install windows 10 creator update, But I did not like it. After installation Microsoft shows downgrade option early after upgrading to Windows 10 and remove it after one month. I recently upgrade my windows 8.1 Professional operating system to windows 10 Professional being getting a license from ODosta Store
    But I did not like its overall structure. I think Its not Windows 10, Its version should be windows 6 as it has many faults.
    I tried to downgrade back to my existing win 8.1 os and I saw as Microsoft was giving me option to downgrade. I thought that I'll downgrade after two month But after two month when I tried again, Microsoft removed that option. Now what to do. I searched and found your post, Which is very helpful for me. Thanks for sharing these details here.

  2. AFAIK, Windows-7 or Windows-8 to Windows-10 is still free (thru Accessibility loop-hole) until Dec 31, 2017. No need to buy Windows-10 license and a machine missing Windows-7 or newer is probably not worth upgrading anyway. Keys from 32-bit versions should work on better 64-bit.
    Just like the old-days ... a Nuke-and-Pave (format and clean install from genuine media) is sometimes the best way to install or re-vert back to an older version.
    Windows-7 is old. The latest version of Windows-8 is Windows-10. I don't think you get to pick versions or say you don't like it. Like on your phone or tablet, you run the latest version. If you don't like Windows, maybe try a Mac (especially if you carry and iPhone). If you carry Android, maybe try a ChromeBook or Linux.
