Windows 10 with Paperless Tip; from a posting on Sage City.
Windows 10 (32 and 64-bit) Pro and Enterprise is only supported with Sage 100 2016 at this time.
The SPM for 2015 should be updated around the end of February. The goal is to have Windows 10 be compatible with 2015 PU4 which is scheduled to release around the end of February or beginning of March
With Windows 10 comes a new setting (turned on by default) of allowing Windows to manage the default printer. When on, Windows 10 will change your Default Printer to the last one used. I found that this was what caused most of my Paperless grief.
The resolution: In windows 10 settings, go to devices and view the Printers and Scanners section. At the bottom of the listed devices is an option to ""Let Windows manage my default printer"". Turning that off restores the old behavior of leaving the default printer unchanged. This (so far) has cleared up all my paperless problems. Been running Sage 100 ERP 2015 Standard on a Windows 10 workstation for about 2 weeks now with no apparent issues.
From a posting on Sage City reliability is at face value.
