• She’s still not great at troubleshooting.

    I’m sure that’s at least partly because Microsoft products are proprietary and many of their inner workings are undocumented, which is a really bad combination if you’ve got an obscure problem you need to troubleshoot.

    One of the many reasons I like Linux is that there’s nothing mysterious about it. Most of the system is reasonably documented, and all of its source code is publicly available. If something is broken, it can be fixed. Nor are there any special restricted uncopyable files; if I need to move the operating system to a different storage device, all I have to do is boot from a USB flash drive, partition the new storage, format the partitions, and copy all the files. (This used to not be the case before UEFI, but now the boot loader lives in a regular file on a plain old FAT32 file system, so it can be copied just like everything else. It can even be RAIDed!)
