Microsoft's fix for 'data damage' risk hits PC performance
Microsoft has warned that Windows devices with the newest supported processors might be susceptible to data damage, noting the initial fix might have slowed operations down for some.
The data damage warning turned up in a support article and is related to devices supporting the newest Vector Advanced Encryption Standard instruction set.for Windows 11 was about CPU security and experience, but here we are. The issue also applies to Windows Server 2022. The fix is, as ever, to bite the bullet and apply Microsoft's updates. The June 23 patch preview release or July 12 security update should resolve the issue, although both carry their own complications. The July 12 patches , for example, left the Start Menu inoperative on some Windows 11 machines, resulting in a Known Issue Rollback for Microsoft.
The good news is that Microsoft reckons the data damage issue was already addressed in the May 24 patch preview and June 14 patch release. The bad news though is that performance was then affected for some users who applied those updates. BitLocker, TLS and Disk throughput were hit and, according to Microsoft,"AES-based operations might be two times slower after installing the Windows update for the May 24, 2022 preview release or the June 14, 2022 security release.
