Reporting record
Finding
Claude for Windows version 1.49585.0 contains new Microsoft-specific enterprise authentication infrastructure, including explicit support for Entra Continuous Access Evaluation, a local Windows authentication broker and additional enterprise credential paths.
How we verified
Methods: documents, reverse engineering.
Static analysis of Claude for Windows versions 1.49585.0 and 1.46388.4 identified new CAE configuration markers, default-enabled CAE, Microsoft cp1 capability references, local broker code, enterprise credential options and sovereign-cloud handling; Microsoft and Anthropic documentation provided context.
RuntimeWire compared the two distributed Claude for Windows binaries, examining application resources, configuration markers and authentication code, and compared the findings with Microsoft and Anthropic documentation.
Tested versions:
- Claude for Windows 1.49585.0
- Claude for Windows 1.46388.4
