I have also just done a Windows 10 repair which completed, but made no difference.

Anyone have any thoughts at all.

Appreciate the look Thx

Try to reset the app itself under advanced options.

Thanks, but no it did not work...

hmm

Updated windows error has changed slightly now getting:

The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID Windows.SecurityCenter.WscBrokerManager and APPID Unavailable to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

The server microsoft.windowscommunicationsapps_16005.13426.20920.0_x64__8wekyb3d8bbwe!microsoft.windowslive.mai l did not register with DCOM within the required timeout.
