June 30, 2026 — Microsoft will transition what it calls its “critical products and services” to post-quantum cryptography (PQC) by 2029, four years ahead of the completion date it published ten months ago, the company announced Tuesday in a blog post by Azure Chief Technology Officer Mark Russinovich.

The announcement accelerates the Microsoft Quantum Safe Program (QSP), the company-wide migration effort Microsoft formalized in 2023 and laid out publicly in August 2025. That roadmap ran in phases: core infrastructure migration starting in 2026, integration into Windows, Azure, and Microsoft 365 from 2027, early adoption of quantum-safe capabilities by 2029, and full transition by 2033, positioned at the time as two years ahead of the 2035 deadlines most governments had set.

The revision cuts four years from that completion date and aligns Microsoft with Google and Cloudflare, both of which committed to 2029 targets for their own post-quantum migrations earlier this year.

Russinovich attributed the change to progress in quantum research and development, which in Microsoft’s assessment has moved the risk closer: the company now expects cryptographically relevant quantum computers on a shorter timeline than its earlier planning assumed. Asked by BleepingComputer what falls within the accelerated scope, Russinovich said it refers to “the entire portfolio of Microsoft’s products and services.”

The post cites two government actions from the preceding two weeks as evidence that the transition is already underway: the June 22 U.S. executive order on securing the nation against advanced cryptographic attacks, which set 2030 and 2031 PQC migration deadlines for federal civilian…
