I took the plunge and installed Windows 10 on one of my laptops. I found that the SMB shares on my HDR-FOX units were no longer accessible on the laptop after the upgrade. At first I was worried that it was a problem with the version of Samba on the HDR-FOX. It isn't that, thankfully, but Microsoft have disabled unauthenticated network shares by default. To enable such shares you have to add an entry to the registry. There is a really good article here that explains exactly how to do this: it takes about two minutes. The fix works, but I had to reboot the HDR-FOX to make the shared folders appear on the Windows 10 machine again.
