Just a suggestion but take a look at this list… all of them should be either open source or at least free (trials, lite versions, etc.).

Find out what you use at work and see if there’s a trial version or if they use open source.

If not most of these tools are known and you may be able to find help online (forums, Lemmy, Reddit, etc.).

Yeah but… will they actually remember where they buried their acorns?

Sometimes the best teacher is experience :)

I have two… these are from the old days of computing :)

One: guy said his monitor was showing wavy lines on the screen (old CRT monitor days). Went to his office, looked at his monitor. Sure enough wavy lines. Looked the top of his monitor. Removed the clock sitting on top of said monitor, no more wavy lines. Don’t put electric clocks on CRT monitors folks.

Two: working in a school system. Just before classes started. Get a call “none of the computers turn on”. Go to the classroom. Check a few machines. Machines “turned on” but didn’t boot the OS. Listen to one of the machines… hmmm, no drive noise. Tap it with the back of a screwdriver. Drive spins up, computer boots. Later found out that it was a semi-known problem with Seagate drives. If they sat to long without use, the heads would get stuck.
