Blog WinBeta claims to have used an early version of Cortana for Windows 10, and the blog says it can do everything the mobile version does. This includes tasks such as setting reminders, making Skype calls, checking the weather, and more.
But Cortana's key feature is missing from the current build, WinBeta writes. The desktop version of Cortana, as it exists now, doesn't have any personality. Microsoft stressed Cortana's personality as being a big part of what makes it stand out from competitors like Siri and Google Now.
WinBeta also emphasized that this isn't the final version of Cortana for Windows 10, so we're likely to see some design changes and a stronger personality if it's eventually unveiled to the public.
