Microsoft admits that the CPU is too advanced and will cause data corruption in Windows 11

Microsoft announced a serious bug in Windows 11 and Windows Server 2022 on its official website, indicating that users of its latest desktop operating system may experience data corruption issues.

Microsoft said the affected systems are equipped with processors that support the latest Vector Advanced Encryption Standard ( VAES ) instruction set, specifically, Intel's 10th-generation Core (Ice Lake) and third-generation Xeon Scalable processors (IceLake- SP), and AMD Zen 4 architecture processors.

Microsoft has released a patch, and the issue has been resolved in the Windows 11 May 24, 2022, Preview and June 14, 2022, Security Patch. However, this patch is not very complete, and after applying these updates, AES-based operations such as BitLocker, TLS, disk throughput, etc. in the system may be half as fast as before.

Users will then need to further update to the June 23, 2022 preview or July 12, 2022 security patch to fully resolve the performance issue.
