Windows 7: Windows 10 Upgrade Fails - 8007002C-4000D

Windows 10 Upgrade Fails - 8007002C-4000D

Hi Guys,

An annoying issue - I've done a lot of research into this issue, and the best thread I've found is over at reddit (

I've tried unplugging every USB peripheral except Keyboard/Mouse, uninstalling Microsoft Security Essentials, doing it from a Clean Boot and disabling all network adapters - and it still fails at about 50% of configuring settings.

If anyone's got anymore advice, that'd be great.

I'm running a SSD with a 1TB Hard Disk.

I've had nothing from the Windows 10 Upgrade App telling me otherwise.

Windows 10 64 bit

I deleted my post after I saw my mistake. Its the Enterprise versions that are not eligible for the free upgrade.
