Despite the fact that logging into your Windows 10 computer may seem simple, there are measures in place to prevent third parties or malware from compromising your system access, so it actually isn’t that easy. Microsoft has taken the security of this system to a whole new level with Windows Hello, which is supported by a variety of services, functions and DLLs.

Recently, some users reported that the error message “Windows failed to connect to the System Event Reporting Service. Please contact your system administrator” when logging into your computer. Some users also reported that they were able to log in, but the same error message was displayed in the notification area. There are several ways to fix this error. You should check the status of several Windows services and make sure that they are running. You should also reset Winsock and run a system file check.

What causes the “Cannot connect to system event notification service” error message?

It is possible to cause this error for many reasons, including improperly shutting down the PC, which can cause the system event reporting service to become corrupt, preventing the PC from connecting to the local SENS server. It is also possible that this error is caused by a failure in the Windows font cache service.

In order to resolve this error, you need to remove the specified update file numbered KB2952664. This update affects the SENS server and is a Windows update that affects it. In the absence of DHCP, the system may not be able to register DNS or IP records, leading to the error.

It is also possible that an antivirus program is preventing services on the network from updating, so Windows Updates cannot push and install updates. If the antivirus program is causing the problem, disable it first and see if that solves the problem.
