Hello all. I have an issue that is above my ability and need some help. I have a dell desktop with Windows 7 64bit. Noticed no updates since June 2013. Tried to update and received a message that the service was not running. Checked services and Windows update is missing. This PC had no antivirus. Cleaned up with malewarebytes and adwcleaner. PC works OK now, but needs to be updated. Also, when I tried to turn on the firewall, I got 0x80070424 and if I try to go back to a restore point I get 0x800423F3. I goggled it and found so many variations so I thought I better post it here since I have always received good advice on this site in the past.
