It's not looking good right now. I cannot load your hive on my Windows 10 desktop, neither can I on my Windows 7 VM. I'll try to load it tomorrow on my Windows 7 work laptop, but if I can't, you'll have to run a repair install of your Windows. What's happening is that your COMPONENTS Hive is corrupted at the point that it cannot be opened anymore, and without it, you won't be able to run Windows Update and you'll encounter a lot of system related issues. Sadly, this hive cannot be "repaired". Sometimes, I manage to mount a corrupted hive which fixes it (no idea what it does), and I then proceed to unload it and instruct the user to swap the old hive for the new one I unloaded and that fixes the issue. In your case, I wasn't able to do that. Do you have your Windows 8 (or Windows 8.1?) installation media?
