After rebooting Windows 10, the IKEEXT service appears turned off - regardless of it previous state - started, stopped, automatically started or manually started. No problem to disable or enable it or run manually. Why the state of IKEEXT can appear switched off?
Here are some methods that you can try to trouble shoot the problem:
1.Make sure that the dependence of the this service is set to automatically start.
2.perform a clean boot to disable the 3-party software conflict.
3.Make sure the service is enabled in msconfig.
4.modify the service to automatic restart on failure.
4.change the startup type of these services from Automatic to Automatic Delayed.
-You can go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IKEEXT\DelayedAutostart
-Add DelayedAutostart entry but set value to 0,If nothing helps, you can check the Event Log to see if there is any related errors generated.
