Microsoft says that Windows 10 users who try to install the update may experience the following error:

This PC can’t be upgraded to Windows 10. Your PC has hardware that isn’t ready for this version of Windows 10. No action is needed. Windows Update will offer this version of Windows 10 automatically once the issue has been resolved.
