Over the weekend, online retailer published what it claimed to be OEM pricing for Windows 10. (Note: To be precise, the Windows 8.1 ERP pricing is $119.99 for Home, $199.99 for Pro and $99.99 for the upgrade from Home to Pro.) Microsoft also plans to charge $99 for the upgrade version of Windows 10 that will allow users to move from Home to Pro, according to the statement Microsoft provided Neowin. In a statement issued to Neowin, Microsoft officials said Windows 10 Home will be priced at $119 and Windows 10 Pro will cost $199. The estimated retail pricing (ERP) for Windows 10 Home and Windows 10 Pro will match the ERP for the comparable Windows 8.1 versions, Microsoft officials said on June 1.
