I wanted to install updates on my computer but whenever I open the windows update settings, it would only load with dots moving above. I cannot enable both the windows update medic service and windows update in the services. They are both disables and I cannot start them. A window saying "Access is denied" would always pop up when I try to set it to manual or automatic. I also changed the value of the Start DWORD to 1 but it would always return to 4. What can I do?
