Hello,Allyson Dyar
Thank you for posting in the Microsoft community.
Currently, the Bluesky social app is mainly developed for mobile and web applications, and a desktop application has not yet been launched. Therefore, you may not be able to use the app directly on your computer for the time being. However, once Bluesky develops a PC version, it is expected to be available on the Microsoft Store. It is recommended that you can feedback your needs and suggestions through Bluesky's official website, so that they can better understand user expectations and invest in research and development faster.
Your voice is very important, thank you for your understanding and cooperation!
Best Regards,
Rota|Microsoft Community Support Specialist
