Xbox executive Kareem Choudhry is leaving Microsoft after more than 26 years at the company. Windows Centralreports that Choudhry’s last day is today, and his departure has triggered a shake-up of some teams inside Xbox. Choudhry’s departure comes just six months after a big shake-up of Xbox leadership and amid continued changes to Microsoft’s gaming strategy.

Choudhry had been focusing on Microsoft’s AI plans for Xbox in recent months, which include a new Xbox AI chatbot that The Verge exclusively revealed earlier this week. Choudhry was also key to Xbox’s backward compatibility support and helped bring Xbox Cloud Gaming to life as xCloud in 2019.
