Microsoft may be in a pickle right now due to the hiccupy rollout of its latest Windows 10 October 2018 Update, but that's not stopping the company from supporting the previous versions of Windows 10. Microsoft announced on its support page that it has paused the distribution of the Windows 10 October 2018 Update (version 1809) for all the users after isolates report of users missing some files after updating. According to a new post from Microsoft, the issue only affected "one one-hundredth of one percent of version 1809 installs", but it was still a large enough problem to cause the update to be pulled. Microsoft says that the majority of modern Wi-Fi printers are compatible with the Mopria standard. KFR is the process of redirecting the known folders of Windows including Desktop, Documents, Pictures, Screenshots, Videos, Camera Roll, etc. from the default folder location, c:\users\username\, to a new folder location. "This occurred if Known Folder Redirection (KFR) had been previously enabled, but files remain in the original "old" folder location vs being moved to the new, redirected location".
Microsoft has now fixed this problem, and Windows 10's October 2018 Update should stop deleting these "old" folders full of files.
We will carefully study the results, feedback, and diagnostic data from our Insiders before taking additional steps towards re-releasing more broadly.
Dona Sarkar, engineering leader of the Windows Insider Program has tweeted that Microsoft is able to restore the removed files.
Users who are affected by the issue are missing files and folders in their "Documents" folder. "We have added an ability for users to also provide an indication of impact and severity when filing User Initiated Feedback".
