    SP1 won't install - "Unknown error" / "Service does not exist"


    Hello - I've repeatedly tried and failed to install Service Pack 1. I have run the update readiness tool, and have run chkdsk and sfc. I've tried installing through Windows Update, as well as downloading the standalone installer from Microsoft.

    The former results in an "unknown error"; the latter results in a window saying that "the specified service does not exist as an installed service" almost immediately after trying. A similar message has come up occasionally in recent days when trying to install a couple of other programs.

    I'm currently out of ideas and would appreciate any help. Thanks!

    Nevermind, scanning with a few anti-malware programs seems to have solved this, somehow. A mod can delete this, please.
