If I upgrade from Win 7 to Win 10, how will it effect my support contract, "Pro Support Plus", which is active through March 2021?
Dell only supports the os that came with the unit.
Upgrading to 10 will not affect any hardware warranty or support. If you want windows 10 support buy retail windows 10 so that you can get help from microsoft.
Windows 7 support ended Jan 14th 2020.
Its now end of life.
