Took my freshly re-cobbled together computer to local computer guy after an upgrade with hand-me-down parts. He asked what was wrong and I said there was an alarm for the CPU fan, and that I'd torn the case open and hooked a second fan into the CPU fan connection and it also didn't work, and the I plugged the CPU fan into a different connection and got it working, so by elimination I was pretty sure the fans were good and the connection in the motherboard was bad.
He seemed mildly amused/impressed by my spiel. I'm not really a computer person, but swapping out parts to narrow down the source of the problem seemed logically basic.
I ended up chilling with him while he worked on things. He found WinZip on my desktop and let out a "whoa retro." which hurt me deeply.
That's exactly what it's for. If you use it commercially without paying winrar will come for you, but as a personal use case it's just ad ware. You get the product, and deal with their ad every boot. You could pay for it, but it probably the least annoying ad on the internet right now.
I remember hearing that they have gone for companies before, but that was a while ago and, ya know, just something I read that may or may not be particularly accurate.
