Problem upgrading to Windows10 from Windows7 Ultimate

Hi,

This issue may arise due to the corruptions in upgrade components and as an initial troubleshooting step.

I suggest you to run BITS troubleshooter and
Windows update troubleshooter and check if it helps.

• Type troubleshooting in the search bar.
  
• Select Troubleshooting.
• Select View all on the top left corner.
  
• Click Background Intelligent Transfer Service.
  

Follow the on-screen instructions to run the troubleshooter.

Check if issue persists.

Once finished with the BITS troubleshooter, now run the Windows Update troubleshooter.

Windows
Update Troubleshooter.

• Type troubleshooting in the search bar.
  
• Select Troubleshooting.
• Select View all on the top left corner.
  
• Click Windows Update.
  

If the issue persists, I suggest you to download
media creation tool
and install Windows 10 using the tool and see if it helps.

Thank you.
