You can build a weapon with common tools you find in any metal workshop.
Story time:
Right after the war my grandfather - a locksmith by profession - build a cap and ball revolver in his workshop just with the tools he had and scrap metal.
Well, as an addition to all the calls for switching to Linux:
Its completely doable to install Windows 11 on unsupported Hardware, using an official ISO from Microsoft and letting the Rufus imager apply a few changes and Win 11 should run on hardware that is about 10 years old or a bit older (i think i have heard Microsoft has removed support for the Core2 generation of CPUs). If you want to get a really clean install the best tool is - i think - tiny11builder which cleans up an official ISO and makes the whole experience of running this OS on older hardware way more pleasant.
Currently i have a test system (a laptop) with an Celeron N3010 and 4 GB RAM on my desk at work running Windows 11 modified by tiny11builder and it is - while not exactly fast - absolutely useable for classical office tasks.
THAT is a story i would be very curious to hear… but if you look at the whole stuff that is build in some huts or caves in the middle east, lets just say i wouldn’t rule it out.
