Nadella admitted that Microsoft's decision to stop developing Windows Phone was one of the most difficult decisions he made.
"The decision that I think a lot of people talk about was our exit from what I call mobile as it was defined at the time," Nadella explains.
Furthermore, he regretted the discontinuation because if development continued, Windows Phone could have found an interesting feature.
"In retrospect, I think there could have been ways we could have made it work by perhaps reinventing the category of computing between PCs, tablets, and phones."
However, the company did not release a smartphone until 2010.
Despite the launch of Windows Phone, Microsoft confirmed in 2017 that it would cease development of new features and hardware for Windows Phone.
According to Joe Belfiore, Vice President of Windows 10, Windows Phone stopped production due to lack of interest and lack of full support from developers to produce more phones.
