I would strongly second this.

I had some down-time between jobs a couple of years back, and used it to volunteer at a charity to help out with some basic IT work.

There was some indeed an element of fixing and securing their WordPress-based website, and sorting out their AdWords campaigns. However, the vast majority of the work (by time, not by difficulty) was cleaning up crapware from Windows laptops, getting Dropbox to work correctly across their machines, and sorting out their software licences after they'd been screwed over by a shady ISV.
