Yet Another Windows Update Done In By The EFI System Partition - PC Perspective

A May Windows security update is failing on some PCs because the EFI System Partition does not have enough free space.

The issue affects Windows 10 and Windows 11 systems where the boot partition is too full to install the patch.

A temporary workaround is to remove font files from the boot partition, but changing the EFI partition is risky.

Users may be blocked from installing an important security update until Microsoft provides a fix or the partition is cleaned up.
