Hello Vescar,
You can search for partners on https://www.pinpoint.com.
In addition, we have tested RMS with Windows 10, and it is compatible, however, we do not test hardware devices, such as receipt printers or cash drawers, and most of the issue we have found have been with these devices.
Before you do upgrade, you will want to contact the manufacturers of these devices to make sure that they will work on Windows 10, along with their OPOS drivers.
Thank you,
Scott Wardzinski
