Hello Mackonen,
We regret the inconvenience. Let me assist you.
Now, before we proceed any further, let us know a few more details on the below questions.
- Did you make any changes to the PC prior to Windows 10 upgrade?
- What is the make and model of the PC?
- What is the complete error message along with the .sys file which shows up?
- Are you able to boot to Windows desktop under any circumstances?
As an initial recommendation, I suggest you to check if you are able to start Windows in Recovery Environment.
Windows Recovery Environment (Windows RE)
Refer to the section Entry points into WinRE
- Once you are able to access the Recovery Environment, perform a System Restore.
Troubleshoot > Advanced options > System Restore - If prompted, click/tap on an administrator account you want to provide credentials for.
- If this is your first time doing a System Restore, click/tap on Next.
- If you had previously done a System Restore, select (dot) Choose a different restore point, and click/tap on
Next.
- Select a restore point that you would like to restore Windows back to.
- Review what will be affected by using the selected restore point. When finished, click/tap on
Close.
- When you are ready to do a System Restore with a selected restore point, click/tap on
Next.
Write to us with the updated status and the required information related to Windows 10 performance, for us to be able to assist you further.
Thank You.
