My computer was working fine. I went to reboot it & it wouldn't come back up & my internet wouldn't connect anymore,keeps saying that the Diagnostic policy Service has stopped working. I did have the codes that was sent for the Windows 10 upgrade,I deleted those. I have done several system restores to no avail. I get Error codes like OX8024402C OX8004001 & 8007371B (KB2913608) when I try to to see why Windows doesn't start. Am I making any sense to you?
