Also, if something does break, it is never impossible to fix it if you are willing to dig and tinker until you find it.

In Windows, there are things that can break that are not documented or accessible, so you literally can encounter things that cannot be fixed by the end user. That’s where the common saying “nuke & pave” got applied to Windows troubleshooting, since you often have to nuke Windows and pave over it with a reinstall to fix a problem.
