First enterprise technology project, after telling the IT director I just hacked the PC's credentials.
I was in 5th grade at the time and I had a year of "consulting" fairly regularly in my small town area under my belt, so I was feeling bold.
I approached my elementary schools IT director after noticing an issue with the sound card drivers in our windows machine. I told him I figured out the admin password on XP with a CD-toolkit, rolled the driver back, and got the computer working again. He thankfully took a gentle approach and didn't just reprimand me for out-of-bounds behavior. That was my first soiree into Group Policy Objects as he was kind enough to have me do the work as he explained how it all operated together behind me. I had a tendency to just do what I felt was right for the world, and he helped me channel that into constructive energy in technology.
He was also coincidentally named Mr. Q, which brought me full circle when some of my own elementary IT students called me Mr. Q some 10 years later in one of Connecticut's smallest districts.
I completed several assignments over that year every day after school (installing access points, wireless projectors, patching windows hosts, learning about AD) and scored the 5th grade honorary title of "assistant IT director" to which I was ecstatic about then.
