First thing, stop trying to fix it.
Windows Update will take its own sweet time doing some updates. Hopefully nothing has gotten messed up, so let it go a few days and see what happens. After seven months, there are quite a few updates....
If you want, you can copy the WindowsUpdate.log from the Windows folder to the desktop. Copy the last few days of entries and then paste into notepad and zip and attach using the paperclip. If something is going wrong, maybe someone will see what it might be.
