1. "Same thing on two computers - home & office. "Do not download or install" is set, but update installed anyway" = again that is normal. Anytime you have WU set to anything OTHER than totally disabled, the WU plumbing will get automatic updates.
2. the second message is not related. Office click to run does not use the same mechanism to update as Microsoft update - it uses a streaming process to automatically download and install the Office updates.
The two symptoms are not related.
