Last month, reports of SSDs failures after installing Windows 11 update KB5063878 quickly raised alarms among users. At first, many suspected the update itself was to blame. However, storage maker Phison and Microsoft also clarified that retail SSDs are unaffected. During the last weekend, while PCDIY group on Facebook linked the SSD failures to engineering firmware present only on review samples. Phison has also confirmed the PCDIY’s report earlier today by issuing a statement.
In other words, regular consumer drives remain safe, and the issue is far narrower than initially feared. However, if your SSDs have been affected, uninstalling Windows 11 24H2 KB5063878 update is the only solution. In this guide, we’ll walk you through each and every step on how to fully remove the alleged faulty update.
