Recovery tools broken, SSDs vanish under load
What broke
August’s update broke the one thing you need most when updates break things: the recovery tools. “Reset this PC” and “Fix problems using Windows Update” both stopped working, leaving users with no self-service repair options when things went wrong. As a bonus, SSDs would disappear entirely under heavy workloads — transferring 50GB or more could make your storage drive vanish from the system. Enterprise deployments via WSUS and SCCM also failed. Microsoft broke the safety net, then broke the thing the safety net was supposed to catch you from.
