All the Windows 10 laptops have the latest version with the 2017 Fall Creators Update and fully patched up.
I’ve experimented with switching clients but unfortunately there aren’t that many out there and the few I’ve tried have not gotten good reviews from my Windows 10 users for various reasons. Spark was the one client that did what we needed it to, but unfortunately it’s not very usable for laptop users if the user has to constantly babysit it’s connection.
