Microsoft’s August 2025 update (version KB5063878) caused significant issues for Phison-branded drives, leading to data loss, drive disappearance, and permanent corruption, attributed to a pre-release firmware issue. The 2018 Windows 10 update (version 1809) also resulted in users losing large amounts of files. Smaller problems, such as performance issues with gaming due to a new security feature in Windows 11, are common after updates. Compatibility issues, like the TPM 2.0 requirement, can force users to upgrade hardware. Updates can lead to performance problems, including slow application launches and crashes. Rolling back updates is often a solution, and users are advised to back up important files and create a System Restore snapshot before doing so.
