The build number of the Windows creator update are not yet present in Lansweeper as of version 6.0.0.63, it will be added to tsysOS with our next update. Until this entry is added, Windows 10 pc's on this version will not be listed in reports that use tsysOS (many built in reports use that table to identify the OS).
If you wish you could already insert the data yourself using a database script, if you mail us at support@lansweeper.com we can provide you with said script.
