Windows 10 April Update and problems printing to shared printer on a Mac

After installing the Windows 10 April update on my laptop I couldn’t print to the shared printer attached to my Mac any more.
I didn’t remember how I originally got the printer working but I already had Bonjour installed. Bonjour is the recommended way of remote printing between Windows and MacOS (download Bonjour from Apple here https://support.apple.com/kb/DL999)

When I tried to find and connect to the remote printer this time I got the message: “Error 1796 You do not have sufficient access to your computer to connect to the printer”.
My account has Admin rights so that shouldn’t have been a problem. I located where the Bonjour executable was found and right clicked to ‘Run as administrator’ but that gave the same message.

I searched the web but couldn’t find any solutions that worked so I have documented what worked for me below.

The solution: I downloaded the latest version of Bonjour and ran it. It gave me the option to Change, Repair or Remove. I removed it. Then digging around in C:\Program Files and C:\Program Files (x86), I noticed that Bonjour folders were still present.
I went into Windows System \ Control Panel \ Uninstall a program and Bonjour was listed in there. I uninstalled and rebooted. There were no longer any Bonjour folders on the disk. I ran the Bonjour installer again and then ran Bonjour Printer Wizard – this time it found my printer, when asked to select a model there is a fairly meaningless list of options. For my Brother printer I chose the last in the list: Brother PS Class Driver in the hope that was PostScript. It worked fine and no Error 1796 message.

I can now successfully print via the remote printer again.
