What needs to be done to securely return a laptop to a retailer?

Windows 10 laptop purchased new, very recently, is being returned. I've logged into my microsoft account during setup and installed chrome which manages my passwords. Im wondering if there's anything that needs to be done to make sure the MS login info and chrome-managed passwords can't be recovered from this device.

I uninstalled chrome and every other bit of software that I installed and am performing a "free space wipe" via Glary Utilities, so I'm guessing chrome will be set, if that was even a risk, but I'm not sure about the microsoft bit.
