Windows 10 Upgrade for Surface Pro 2

Hi,

Has anyone, with a Surface Pro 2 and Windows 8.1 Pro Update 64 Bit, completed a Windows 10 Upgrade?

My two other machines had no problem upgrading, one a 32 bit and the other a 64 Bit.
Both have almost identical software profile to my Surface Pro 2.

I believe I have tried most of the advice available such as :-

Uninstalling CIS, MBAM, Secunia, Keyscrambler, K-Lite

Using Autoruns to untick Logons, Codecs, Scheduled Tasks, Services, Drivers(some!)

Plus Clean Boot.

I have run SFC and DISM.

The last try I did all of these.

I have tried the upgrade via Windows Update (umpteen times!) but also using the Windows Media Creation Tool
The only difference with the latter was the extra message :-
The Installation failed in the SECOND_BOOT phase with an error during PRE_OOBE operation

I always get 8007002C-4001E error after the Upgrade has reverted to the previous version of Windows.

Regards
