Here are the step-by-steps on upgrading to Windows 10. I'm using a Dell Vostro v131 laptop for the upgrade. The current Operating System on the laptop is Windows 7 Pro Service Pack 1. I actually pushed the upgrade manually to my machine because I didn't want to wait for Microsoft's pop up to notify me that upgrade is ready.
