Hi Peter,
The Windows Features dialog box starts off as a greyed out box and says "please wait." Then after 58 seconds delay it fills in and displays normally.
Also, Windows Update fails with error code 80072EFE and checking for updates in Windows Defender fails with the message "The program can't check for definition updates. Error found: 0x80072efe. The connection with the server was terminated abnormally."
However, my internet connection seems stable and is functioning just fine.
Additionally, I cannot get Windows Process Activation service to start. The service is set to automatic start but doesn't actually start. Attempts to start it manually gives an "Error 2: The system cannot find the file specified."
