Users are reporting that the update named KB5063878, released for Windows 11, is causing serious malfunctions on computers. According to information, after the update is installed, cases of the system not booting, disk partitions not being recognized, and complete data loss are being widely observed.
The editorial office reports that complaints specifically mention SSD drives falling into RAW format, making data recovery impossible. Users state that the update was released in August, but the problem has not yet been officially recognized.
According to claims, computers with disk usage above 60 percent are more affected, and the system completely stops functioning immediately after the update. It is emphasized that the only solution is to roll back the update.
Experts note that what is happening poses a serious risk and users should act with caution. Microsoft's lack of an official statement on the matter is increasing concerns.
