Hi there, I'm suffering from a persistent error which prevents me from installing Windows 10.
I've tried the simplest tip:
It downloads > 2 GB and says "Checking prerequisites", but after a while it ends with error 0x8007007B. It doesn't get to the actual installation.
So I tried clearing the ~$Windows.~BT and $Windows.~WS folders on C:\ and reran the steps above.
Failed. So I dug a little deeper and found the following tips some of which I've run several times already:
Running some of these tips corrupt my network card driver and the only way to fix this is by restoring a previous Restore Point.
The windowsupdate.log reports some warnings:

So you might wonder why I didn't just use the Media Creator Tool and create a bootable USB stick -- well, it doesn't run. When I double-click it, it opens and closes immediately. It creates the ~$Windows.~BT folder and quits without doing anything. It quits so fast you can't even see it running in the task manager.
Unfortunately I don't have any Windows 8.1 install media available but given the fact that sfc /scannow reports no corrupted system files I assume it's not needed to restore any files and the problem must be in another area?
Any help would be greatly appreciated. I hope I've given you some ammo to work with, otherwise I'd be happy to provide more information. Thanks in advance!

I've tried the simplest tip:
- Clear the C:\Windows\SoftwareDistribution\Downloads folder
- run wuauclt /updatenow
- Click Windows Update
It downloads > 2 GB and says "Checking prerequisites", but after a while it ends with error 0x8007007B. It doesn't get to the actual installation.
So I tried clearing the ~$Windows.~BT and $Windows.~WS folders on C:\ and reran the steps above.
Failed. So I dug a little deeper and found the following tips some of which I've run several times already:
- sfc /scannow (finds no corruptions)
- the Windows Update fixer from the Windows 8.1 Troubleshooter (says it fixed something but when I run it again, it fixes the same issues so I doubt if it really does anything)
- the Windows 8.1 Fixit solution (says it fixed something but it doesn't fix my problem)
- dism /online /cleanup-image /scanhealth (finds no corruptions - comes back 100% fine)
- rundll32.exe pnpclean.dll,RunDLL_PnpClean /DRIVERS /MAXCLEAN (corrupts my network card, doesn't fix anything)
- reset winsock and reboot
- some more tips I picked up from the Microsoft Support site, such as "disconnect any removable media before running Windows update", to no avail.
Running some of these tips corrupt my network card driver and the only way to fix this is by restoring a previous Restore Point.
