If you have trouble opening the Start menu or Cortana after updating your PC to Windows 10, try out the resolutions listed below. These are the basic troubleshooting options including restarting system, resetting and using Start menu troubleshooter.

However, note that Cortana is available in the following regions for these languages; Australia (English), Brazil (Portuguese), Canada (English/French), China (Chinese simplified), France (French), Germany (German), India (English), Italy (Italian), Japan (Japanese), Mexico (Spanish), Spain (Spanish), UK and US (English).
