So my computer decided that I was running low on space on my boot partition. (Which I was, for some reason.) It wouldn't let me delete files it said could be deleted, and was insisting on installing a bunch of updates the next time I shut down. So I had to back up everything on the second partition, delete it, expand the boot partition into that space, recreate said second partition out of what was left, and copy everything back. Thankfully, since it has the same drive letter, all my programs appear to work as they did... but after only about fifteen minutes the OS has eaten up 7% of the extra space I gave it on the boot partition. (To be fair, more than half that was the updates, but still.)
I can't be too irked, though, since this is partly the result of my own idiocy in making the boot partition too small when I set the thing up.
