Will we get fixes for remote code execution attacks? Fixes for privilege escalations? Will we get…? Oh, you don’t get verklempt, excited, and in a tizzy? You actually dread Patch Tuesday?

Several years ago, when Microsoft rolled out the feature release version of Windows 10 1809, some users reported losing files and folders during the process. The problem caused Microsoft to pause the feature update to investigate what was triggering the issue. As it turned out, the root cause was not the update — it was the timing and rollout of a feature in One Drive. As Microsoft noted in a blog post at the time, the culprits involved three different scenarios with Onedrive — in particular, a setting called known-folder redirection. Although the issues were not widespread, the damage and loss of trust in the Windows update process was immense; even now, users remember that issue when updates arrive. Microsoft revised the 1809 release to deal with the problem and loss of data did not recur afterwards.
