Screen sharing not working after 1809 update

I recently upgraded to the latest version of Windows 10 that is being released (v. 1809). 

But after that i realized that I'm not able to share my screen/desktop/Window.

Sharing panel pop-up with  Connecting status. After several seconds its ends with message in chat: "The invitation you sent to.......expired."

Tried that with several users with different versions of Skype.

Hi All,

Was finally able to resolve my issue with the help from Vikash at Office365 Support.

I found the following registry entry is missing. You will need to run regedit as Administrator to add the entry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

When you get here, click on Parameters - do not expand list - look for the parameter, MaxUserPort

NOTE: This is not plural - make sure spelling is accurate.

If this is not defined, please add the following:

New DWORD

Enter the name: MaxUserPort

Hit Enter to Accept the name.

Right click on the new entry and select Modify

Select Decimal and enter 5000 as the value.

Hit OK to accept new value and exit the dialog.

(15000 was recommend to test with. Then I reduced to the default in my final implementation. The reference to default value I took from here: 

https://support.microsoft.com/en-us/help/196271/when-you-try-to-connect-from-tcp-ports-greater-than-5000-you-receive-t)

Then Reboot your machine and give it a whirl!

Hope this helps!
