Microsoft abruptly suspended developer accounts that maintain several high‑profile open‑source projects, cutting off the ability to publish Windows drivers and security patches. Affected tools include the WireGuard VPN, VeraCrypt encryption suite, MemTest86 RAM tester, and Windscribe VPN client. Developers lost access to the Partner Center portal, leaving Windows users without critical updates.

Microsoft later clarified the bans stemmed from an automated “mandatory account verification” required for participants in its Windows Hardware Program. The policy, announced in October 2025, gave partners 30 days to complete the process; accounts flagged as “Rejected” after the deadline were automatically disabled. Vice‑president Scott Hanselman said the rollout had been communicated via emails and banner notices since October 2024.

Project leads such as WireGuard maintainer Jason Donenfeld and VeraCrypt creator Mounir Idrassi have pressed Microsoft for reinstatement, citing risks of unpatched vulnerabilities on the dominant Windows platform. After media coverage, Hanselman promised a near‑term fix, while EVP Pavan Davuluri pledged to improve notification procedures. The incident underscores how automated compliance checks can disrupt open‑source tooling. Without timely patches, enterprise customers may face exposure.
