After upgrading to Windows 10 Pro 'November' release (version 1511, 10586), I found that all my extra printers had disappeared and I had to re-install all of them - this applied to the printers I had set up to use the same physical printer, but with different printer preferences.
Also, many of the links between file types and applications had reverted to some useless Microsoft applications. For example my PDF files, which were set up to open Adobe Acrobat Pro, I found they opened in MS Edge web browser!!
I have had to go through them all to change them back to sensible values.
I do wish MS wouldn't assume that everyone want to use their applications!
