I love my inlaws, but Great Googlymoogly with the IT support. I am pretty handy with technical stuff - computers, printers, tablets, iCloud, TVs, etc. DH is adorable, but believes the internet is a series of tubes. DH's parents know less, so I end up taking care of their stuff, too. For a long time, this was very stressful and difficult, because while MIL was very grateful and sweet about it, leaving me alone to handle the problem, FIL would stand behind me while I worked on their computer, pacing and fidgeting and grumbling and telling me, "NO! Don't click that!" and "NO! Don't tell them that!" while I tried to convince him that defragging his hard drive wouldn't give the "identity thieves" his bank account information.
Finally, I told my MIL that I was more than willing to continue helping them with their tech support, but in exchange, I had three demands:
1) If FIL was going to continue email correspondence with friends overseas and clicking on links they sent him, I would be allowed to install some sort of internet security program to protect them from the very scary viruses that were infecting their hard drive.
2) MIL would contact me and explain the problems they had with any given device.
3) FIL wouldn't be in the room while I tried to fix the problem.
So far, it's worked out
My dad is very tech savvy, thank goodness, so he takes care of my parents' stuff. I don't know what I would do if I had to take care of my parents' tech, too.
