Windows 10: How to restore laptop blue screen error and won't boot after editting the registry...

Hello there!I am very desperate right now, since all my important files and documents are inside my laptop right now. I changed my User value in ProfileList inside regedit hkey local machine. Whenever I boot up my laptop, it won't let me go to the sign in page, instead to the bluescreen page. I have tried the restore option to 2 days ago, 23rd February, but it didn't work and gave me an error. I have also tried signing in with all safe modes and it threw me errors. I tried resetting the laptop without losing any files, yet it still threw me errors.

Hp laptop screen won’t display except occasionally

I would like to note that step 20 comes up with no files. Perhaps this could be the source of the issues?

 

Error. Blue Screen

Hi,

In addition to the above mentioned solutions by Community members, I would like to add the following:

Before we proceed I would like you to answer the following question:

• 
  What is the make and model of your computer?
  
• 
  Did you make any changes prior to the issue?
  

The issue might occur due to Viruses, or something changing/deleting in Registry Files, a failure during Bootup, or a corrupt file which could be due to age of a computer or viruses or somebody tampering with files.

I suggest you to follow the step below:

Blue Screen and Error code: 0xc0000428 on Startup

Hello,

When I start my computer the screen is blue and reports:
Digital signature for this file couldn't be verified
Error code: 0xc0000428
You'll need ti use recovery tools. If you don't have any installation media (like a disc or USB device), contact your PC administrator or PC/Device manufacturer

If I press F1 for Recovery Environment then I just return to the same blue screen and error message. If I press Esc then I can get into BIOS and choose to Boot from UEFI installation media.

First, let me say that I have Googled and tried pretty much every suggested solution out there but I still haven't been able to fix this issue.

Computer information:
Asus Laptop
Windows 10 Home

It started when I turned on my computer yesterday (worked the day before), the only difference is that I had plugged in headphones when I started the computer (the headphones I had used before on numerous computers).

To try and solve this I have:
- Downloaded the MediaCreationTool and created an installation Media (to have USB to boot from)
- I tried every System Repair and Restore (from Troubleshooter) but nothing worked. System Restore just restores to last known point (have tried different points) but the same blue screen error occurs.
- I tried to install a new Windows but I still get the same error (and now I can't do System restore since there are no previous saves)
- I have gone into Command prompt and tried Chkdsk and it reports no errors except that it was unable to save message log.
- I even tried to recreate the Registry by using CMD but when I came to the step to go into RegBack the directory is empty of any files (no Registry files so can't perform back-up)

So if anyone can help me figure out how to restore my computer it would be highly appreciated since it feels like I have tried everything.
