Windows update continues to swamp the hard drive with files, making the apps unusable, which adds a good bit of keep-it-running upkeep time to the daily tasks. Additionally, something about the connection at the research libraries makes a DISM repair impossible, and it would require more than the hour or so in which I can plausibly hold down a chair at the cafe on the strength of some peanut butter and bananas. Will have to find another patch-in point for the matrix.
