SOLVED: windows update service not found – Dell Inspiron 15-5559

i have some problem i don’t know there are because of the same problem or not?

firstly: the windows update has a problem and i can’t update or install from Microsoft store

the message is “Your device is missing important security and quality fixes.

There were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070424)”

secondly: i don’t have the windows update service on services and every-time i run the wuauserv.reg and restart the pc it fails.

thirdly: on the task manager the “svchost.exe” Host Process for Windows Services is running continuously with high CPU and the pc is very very slow
