Windows Can Not Connect to the System Even Notification Service

[Margo1]

I turned on my computer and the following happened:

It was recommended I do the disk check to check for consistencies on Disk C, so I did this. No message came up.

Then I went to my home screen and the message "Failed to connect to a windows service" came up. The rest of the message said "Windows could  not connect to the System Event Notification Service service. Prevents some users from logging on. Review the System Event Log."

As I was clicking on various functions on the Start Menu, I clicked on something (I can't remember where) that stated that the "DHCP client service is not running on this computer."

When I attempted to work with a genealogy program called Roots Magic 7, the message "Error on loading Winsock 2 library (WS2_32.DLL)" came up.

My computer keeps on stating that I have no Internet connection even though I contacted my ISP and the representative said my connection was fine on their end and my cables were all secure.

What do I need to do to correct this problem?

Thank you very much for the solution!  I actually bought a new Windows 10 computer in between the time I started experiencing the problem and the time I received the solution, so I have some questions I need to ask that could possibly help me in the future with my new computer should I experience problems.

1)What caused this problem to happen in the first place?

2)Does the fact that this Windows Vista computer is not receiving Windows updates anymore have anything to do with the problem?

3)Is there any book that you could recommend that would have software troubleshooting information so that a novice could troubleshoot the problem herself?

It looks like you were interacting with @sandytechy20, but he is out for the day & I'll be glad to help you out,

1) This an application designed for use by mobile users require a unique set of connectivity functions and notifications. In the past, these individual applications were required to implement these features internally. The System Event Notification Service (SENS) now provides these capabilities in the operating system, creating a uniform connectivity and notification interface for applications. Using SENS developers can determine connection bandwidth and latency information from within their application and optimize the application's operation based on those conditions and is outdated.

2) Yes, it does as mentioned above, it's an obsolete service, considering Microsoft is pushing all users to upgrade to win10 as all other versions will not be supported in the near future.

3) I'm not sure about books, however, here's a link to Using Automated Troubleshooting to learn more about windows and troubleshoot accordingly: Click here
