I assume development chose the build number because the OS name might not be uniform across language-specific OS releases. I've created a ticket for development to get the new build number implemented, but I'm not sure when a new Lansweeper update will be available.
You can manually resolve the issue by executing the script below in the Configuration\Database Scripts section of the web console. The script adds an entry to tsysOS. Copy and paste the code and hit the Execute SQL Code button. To be safe, back up your database prior to running any scripts. Backup instructions can be found
here.
INSERT INTO tsysOS(OScode, OSname, Image, Sortorder) VALUES('10.0.14393', 'Win 10', 'ten10.png', 18)
GO
