Ahem. Sorry. I just could picture it sooo clearly. My exes, as well as my current SO have all been geeks -- dunno why, since I'm not one. Unlike your DH I am so overjoyed to have built-in, at-home tech support that not only do I have zero desire to perform any maintenance tasks myself, I am so lazy I don't even de-frag my own hard drive. And AVG is set run automatically every night b'coz left to me...it'd be done about once a month.
So what maintenance tool do you use that you're loving so much....? And just a thought, but have you considered not
giving DH administrator -- or even power user-- privileges...? Esp if you're networked? Jus sayin.
