Corrine Posted May 2 Share Posted May 2 From Microsoft won't fix Windows 0x80070643 errors, manual fix required: Microsoft has confirmed that it won't provide an automated fix for a known issue causing 0x80070643 errors when installing recent Windows Recovery Environment (WinRE) updates. The problematic updates were issued during the January 2024 Patch Tuesday to fix CVE-2024-20666, a BitLocker encryption bypass vulnerability that allows attackers to access encrypted data. The issue impacts Windows 10 21H2/22H2 (KB5034441), Windows 11 21H2 (KB5034440), and Windows Server 2022 (KB5034439). On affected systems, it mistakenly shows generic '0x80070643 - ERROR_INSTALL_FAILURE' error messages instead of the correct CBS_E_INSUFFICIENT_DISK_SPACE error on systems with a Windows Recovery Environment (WinRE) partition that's too small for the update to install. Additional information is available in the referenced article including links to the Microsoft articles with steps that will allow the installation of the update to succeed. 2 Quote Link to comment Share on other sites More sharing options...
