It's impossible to say if there is a version of Stonex Survey Office for Windows 10 or not, because there is no website to acquire this information from. I've checked Google Search and all the related websites, but couldn't find anything about it. If you have the software installed, go to Help > About and use the available data to get in touch with the developers. They should provide additional information regarding their product.
Unfortunately, this is the only way to get details about compatibility and the status of the software.
