Microsoft has warned today that Windows devices with the newest supported processors are susceptible to data damage on Windows 11 and Windows Server 2022.
"Windows devices that support the newest Vector Advanced Encryption Standard instruction set might be susceptible to data damage," the company revealed today.
These Windows updates also come with a performance hit since AES-based operations might be two times slower after installing them on affected systems running Windows Server 2022 and Windows 11.
"We added new code paths to the Windows 11 and Windows Server 2022 versions of SymCrypt to take advantage of VAES instructions," Microsoft said when describing the cause of the issue.
"SymCrypt is the core cryptographic library in Windows. These instructions act on Advanced Vector Extensions registers for hardware with the newest supported processors."
Microsoft says these Windows updates will restore initial performance metrics once installed on affected devices.
