I'll add for a few more details to help you with your laptop setup:
1. Touchpad adjustments are located in Devices\Mouse & touchpad. Click on the "Additional mouse options". On my Dell laptop, this brings up a Dell Touchpad control. I believe HP has something similar to adjust the sensitivity.
2. Shutdown after 5 minutes: Settings are in System\Power & sleep. Adjust per your needs.
3. Cortana: It can be turned off. Please read this link: https

Hopefully, with some tweaks, you'll get used to your new laptop and Windows 10. Please post again if you run into other issues. Provide the details of the issue and we'll help you!
