Error: 0x80070424-0x90018, while trying to upgrade to Windows 10 from Windows 7

Hello,

From the error code 0x80070424-0x90018, we got a hint The specified service does not exist as an installed service.

To resolve this, make sure you temporarily uninstall (recommended) or disable third-party AV during the upgrade. Turn on Windows Defender then, using this guide:

Also, disconnect any external devices and perform clean boot:

Now perform upgrade and you'll not get that error.

Hope this helps!
