Windows 10 users with KB5034441 update failure need to manually resize partitions to fix the problem
When Microsoft released the recent KB5034441 update for Windows 10, the aim was to fix a security vulnerability that could allow attackers to bypass BitLocker encryption by using Windows Recovery Environment (WinRE). Unfortunately, the update itself proved problematic for many users.
Microsoft has now acknowledged the issue, noting that users may not be able to install the update and may encounter an error message that reads "0x80070643 - ERROR_INSTALL_FAILURE" or " Windows Recovery Environment servicing failed. (CBS_E_INSUFFICIENT_DISK_SPACE)". The company has a solution, but it's a bit of an awkward one.
