How to uninstall Last Windows Update? A Simple Guide.
Have you ever installed a Windows update only to find your PC acting up soon after? It’s a common issue. While updates bring new features and security fixes, they sometimes introduce bugs or conflicts that disrupt your workflow. When that happens, uninstalling the troublesome update may be the quickest fix.
Recently, the Windows update KB5063878 has been causing notable headaches. Let’s understand what’s going on, and then walk through easy ways to uninstall problematic Windows updates – including this one.
Understanding the KB5063878 Issue
Released in August 2025, the KB5063878 update targeted Windows 11 version 24H2, aiming to improve system security and stability. However, shortly after release, users reported serious storage problems. The update caused certain Solid State Drives (SSDs) to “vanish” or show partitions as RAW, effectively making data inaccessible both in Windows and even in BIOS. This occurred especially during heavy write workload scenarios, such as installing large game patches.
These symptoms hint at a critical bug that leads to SSD data corruption or failure, a serious issue that Microsoft acknowledged and began investigating with hardware partners. If your system started behaving unpredictably, shutting down randomly, or missing SSD drives after this update, it might be the culprit.
Fortunately, uninstalling the update can help restore normal system function until a fix is released.
