This Tuesday is Microsoft’s February patch upgrade day, the first two days of no attention when the upgrade, including a patch number KB4532693, it inadvertently caused trouble for Microsoft, some users upgrade after the desktop, configuration file lost. From user feedback, after upgrading the patch, the desktop and user configuration of Windows 10 appears to have been reset to the default settings, the desktop background has been restored to Windows, the custom icon is gone, and even the files on the desktop are gone.
But the problem isn’t as serious, because Microsoft doesn’t really reset and erase the data, the user’s desktop and profile are still there, and backup files named after .ooo or .bak can be found under the C:-Users user file.
This problem is likely due to the upgrade process, where these users’ accounts are loaded into a temporary configuration, the original files are renamed and backed up, and then Microsoft forgets to change them back to the user because of some bugs or negligence.
Users can retrieve lost desktop files or user configurations through registry editing and folder renaming, but for many users, registry editing and things like that can be a bit difficult.
There are other aspects, either uninstall this update, or restart a few more times, and then it is possible to automatically recover back.
