The European Commission is probing Microsoft for potential anti-competitive practices with its Entra ID security software.

Complaints from competitors like Cloudflare and Google claim Microsoft is unfairly restricting customer choice for security software.

This inquiry follows a previous examination into Microsoft's investment in French AI startup Mistral AI.

Microsoft previously addressed EU competition concerns by offering a lower-priced app bundle without Teams after a complaint from Salesforce.

The EU is vigilant over Microsoft's market conduct, especially regarding agreements with AI developers, hinting at a possible formal investigation into abuse of dominance.

Microsoft's stock slightly dropped amid these developments, despite a significant gain over the past year.
