.RDP files won't open (remote desktop) after Win10 Anniversary Update

After the Windows 10 Anniversary Update was installed on my Windows 10 Pro, .RDP files won't open. Remote Desktop still works if you open it manually and enter in the server info. But my saved .RDP files won't open. Also, right clicking on them and selecting edit also does not work. Nothing happens. I even opened Remote Desktop connection, entered in the server info manually and clicked Save As. That shortcut also won't work. Any ideas on what's wrong? Thanks.

I am having the exact same problem. Also, if you right click on a network computer in File Explorer and click on Connect with Remote Desktop Connection, nothing happens.

I am glad it is not only me. Experts, please help.

I have confirmation that this is an upgrade bug. It does not happen with a fresh install of Windows 10 Anniversary.
It also broke Maccrium Reflect scheduled tasks (Macrium said at their forum that they are working on a fix), removed numerous features (lock screen disable, for example) and likely broke more than just Remote Desktop. I've restored my backup image and turned on defer upgrades in Windows update advanced settings.. This Anniversary update is not ready. I'll wait 3 months. BTW, Microsoft will likely fix this RDP bug in a subsequent update - I would say within about 30 days.

Could this be a 3rd party software break for RDP, from the upgrade? My RDP works fine on 4 PCs so far, that I upgraded.

RDP still works, it is just that it does not work from FILE EXPLORER or from clicking on a .rdpfile.

The Only RDP related software I have installed is Microsoft Remote Desktop Connection Manager v2.7

Have you checked the .rdp for file association? Settings/system/default apps/choose default apps by file type
.rdp says Remote Desktop Connection on mine

Yes, mine is the same.

Parameter support is also broken, to the point where you can not even do mstsc /?

Are you using RSAT tools? Because you need to download and install the version for 1607
