In October 2018 Microsoft released the Windows 10 October Update (version 1809). It was re-released on November 13, 2018. The update fixed many issues (you can see them listed here) but as with many major updates it also caused problems and unintended side effects.
For me the major issue caused by the 1809 update was that it stopped my abilty to screen share on Skype for Business.
As I work remotly from my colleagues this was a very big deal and a problem that I had to find a solution to.
The fix is fairly technical and uses the Registry Editor (regedit) to make changes to your computers registry. If you are not comfortable or familar working with the registry we would strongly suggest leaving it to a professional (you can call us on 01293 562 700!).
If however, you feel up to the task the steps are reproduced below:
You will need to run regedit as Administrator to add the entry.
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:
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.
Then Reboot your computer.
