Windows 10 was released on end of July, 2015. Most of our current version of the structural products which were released in last few months are compatible in this environment.
The search results on Bentley's Software Downloads page display the supported operating systems for each program. You will get this information once you click on the product itself. Consequently, use of the programs on an unsupported operating system is at your own risk.
Please note that Microsoft is supporting backward compatibility with Windows 10 release. So applications which worked fine on Windows 8, should work smoothly on Windows 10.
Does my structural program work under Windows 8?
