Also failed upgrade from Windows 7 to Windows 10 on Thinkpad X230T. Getting “Something happened determining if your PC can run Windows 10”. Discovered Windows Update Troubleshooter, said Service Registration is missing or corrupt, manually copied-and-pasted commands into terminal window for 15 minutes, fixing Service Registration. Unfortunately, still getting “Something happened” message, so will stay with Windows 7 on another computer this is almost always running Ubuntu Linux. Another waste of 3 hours.
