Dona Sarkar is moving on from leading the Windows Insider team. Sarkar led the team for the last three years, overseeing several major updates to the operating system. Sarkar has also made several strides to increase the community of Windows Insiders.

Microsoft did not name an immediate successor to Sarkar in the blog post announcing the move. The blog post by Eran Megiddo, Corporate Vice President of Windows and Education, states that the search for Sarkar's replacement is ongoing.

Currently, we are conducting a search for a new leader of the Windows Insider Program. In the meantime, I and the Insider crew (including Brandon, Jennifer, Blair, Jason, Vivek, Eddie) look forward to continuing to engage with you each week as we ship new builds. And as we've done since the beginning of our program, we'll continue to evolve to best meet the needs of this fantastic community.

Sarkar shared the news on Twitter, adding that she is moving to the Microsoft Developer Relations Azure Advocates team. There, she'll lead advocacy for the Power Platform and tech skilling.
