Here are the notes I took:
If it is a new install you first need to download the latest Windows Update Agent: https://support.microsoft.com/en-us/kb/949104
after it reboots download and run the update patch here: https://support.microsoft.com/en-us/kb/3102810
Reboot again and the updates should work. It still might take a while. From the original installs there are upwards of 200 updates
just in the first pass. Be patient and let it run.
Well. This is X64. I installed the Windows Update Agent. Downloaded the patch to fix the high CPU usage and it did not help. Windows Update is taking up a constant 25% CPU usage and 1.5GB (yes GB). What did I miss?
