Updates confusion

Hi jamis. Apologies for the delay in this thread.

1) I have advised the build, etc, in a post above.

2) Having briefly spoken to someone who knows a lot about this stuff, he seemed to feel the same as you, ie,

the OP is suffering from the KB4090913/KB4090914 corruption.

so the question now is, what do i do about it ?

I am loath to have to re-install W10, and please refrain from any suggestions to play around with the registary, etc, as that sort of thing is way beyond me.

PS, the situation is the same - no further updates have downloaded, and the trouble shooter is useless.

 

I lost access to the microsoft teredo tunneling adapter.

While I was trying to install the Teredo Tunneling Pseudo - Interface, I uninstalled the Microsoft Tunneling Adapter, then I think it turned into an "Unknown" device and so I thought it was useless and so I uninstalled it. I tried using the Hardware Wizard
and it didn't show up. I also tried using the Registary but only the Teredo Tunneling Pseudo - Interface came back and not the Microsoft Teredo Tunneling Adapter. I'm pretty sure anything that requires an adapter won't work without it. Any ideas on how to
get it back?

 

windows 10 upgrade

Hi

I try to upgrade from win 7 "32 bit" to window 10. Registary value for "allow OSUpgarde" value set at 0x0000001.

Every time i try to install window 10, it goes back to arduous download "each time for more than one hour" and then preparation for installing &
Eureka it fails to install!

MS should know better that end users are not all Software Engineers! Error message i get is 800703e6 and much more!

Can any one help? Please no more try this & that! Genuine expert input is appreciated.
