Unfortunately, one long-standing issue still impacts Windows 10, causing users to receive 0x80070520 errors when attempting to change their account profile pictures.
Microsoft is also aware of an issue impacting devices dual-booting Windows and Linux that causes Linux not to boot.
As part of the August 2024 Patch Tuesday, Microsoft released a security update that applied a Secure. Boot Advanced Targeting (SBAT) setting to devices that run Windows to block boot managers with known vulnerabilities that could be used to bypass security boot.
Unfortunately, this caused devices dual-booting Linux on older bootloaders to no longer boot properly, receiving a “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.” error.
Microsoft shared a temporary fix, which entails removing the SBAT update from Windows 10.
A full list of fixes can be found in the KB5043064 support bulletin and last month’s KB5041582 preview update bulletin.
