I already know this is pointless, but it's mildly interesting.
I ordered my eMachines computer from Newegg on 9/9/2009, ten years ago Monday. Coincidentally, the last time I booted the computer was 9/9/2018, so, about six months ago, I thought, "Why not let it run a whole year as a victory lap for its tenth birthday?" Well, here we are. My computer has been turned on for one year straight, and it just had its tenth birthday (although, Newegg didn't ship it until the 16th or 17th, so I didn't receive it for a while afterwards). I finally rebooted it last night to install the pending Windows Updates. Since I have an uninterruptible power supply, I was able to keep this computer running through two rearrangements of my office.
This PC is a horribly slow, bargain bin POS. It served its purpose when I got it, but I only use it as a media server now, mostly to record over-the-air TV.
