1903-1905-1909 all will create problems for peer to peer & SMB network share of printers and folders in windows 10.

Will not create problems for networked printers though. But scanning would sometimes work and not.

Removed a lot of legacy printers support. Could not share USB/ parallel printers easily.

Windows 7 drivers that used to work require reinstallation every minor security update that patches network sharing.

Epson drivers are most common to be disabled through network share.

From 1905 Window XP Home folder/printer shares no longer work even if you have SMB feature installed.

It could be minor problem if you could live with it. Major if you need to do system restore to solve the problem.

The speed of manufacturer issued driver updates for printers are a major issue to solve the problems every new updates posed.

Data loss might happen if you keep a lot of data in DOWNLOAD FOLDER. Windows cleanup after install sometimes clears download folder if the space is deemed inadequate.
