I didn't forget you. I've been busy lately because of all these Windows 10 upgrade threads I'm currently opening your Procmon file which is 14GB big (wow). The ETA for the open time is around an hour, so I might be in bed and just see it tomorrow in the morning.
All good no worries. This allowed me to get a 3GB file only on the process I want to examine. I cannot do that at work so I'll take a look tonight (took me an hour yesterday to apply the filter and save the file).

No problem calcu, you're welcome :) Looks like there might be a solution for those encountering that error code (0x5) during the Windows 10 upgrade after all!
Aug 19 2015 and I was having problem with installing WINDOWS 10 PRO 64 BIT UPGRADE from my WINDOWS 7 64 BIT PRO and error code I kept getting was CODE 80070005 ie"WindowsUpdate_80070005". Most of what I found pointed to errors with various permissions and this is what I worked out and what indeed worked for me and a few colleagues machines and it changes all machines permissions back to default. Some of the fixes CORRECTLY tell you to install SubinACL.exe that is downloaded from SubInACL (SubInACL.exe)BUT they then ignore this installation and incorrectly start messing about with notepad on the desktop. You have just installed subinacl so why mess about with notepad...USE Subinacl and for those with a 64 bit system obviously installing subinacl in system32 is no good as its gotta go into sysWOW64 so double click subinacl.exe that ya downloaded to desktop changing install destination directory to EITHER C:\Windows\System32 or for 64bit its C:\Windows\SysWOW64. Now open a command prompt (CMD) and type: cd C:\Windows\SysWOW64 or cd C:\Windows\system32 which changes directory to where you just installed Subinacl. Then copy the following which is same as above; subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f We the go to command window and right click to paste into the command window which will then proceed to change the permissions to default and THIS DOES TAKE QUITE A WHILE so be patient and wait till complete. When finished I closed command prompt and rebooted and then Windows 10 Pro 64 bit installed ok as did 32 bit versions on other machines...Have Fun :)...I get a notification if you need any assistance but I work so cannot promise immediate replies :)
