Im not sure if it would delete the whole system. Isn't it more likely that it will destroy everything until it kills a file/directory necessary for the operation to run?
The reason you expect this is because Windows has a file lock behaviour that won’t let you delete a file when it’s in use, in Linux this limitation doesn’t exist.
Raymond Chan, arguably one of the best software engineers in the world, and a Microsoft employee, has repeatedly lamented the near malware like work arounds developers have had to invent to overcome this limitation with uninstallers.
Think about uninstalling a game. You need to run “uninstall.exe” but you don’t want uninstall.exe to exist after you’ve run it… but you can’t delete a file that’s in use. Uninstall.exe will always be in use when you run it….so how do you make it remove itself?
Schedule a task? Side load a process? Inject a process? Many ways…. But most look like malware.
Linux has never suffered this flaw.
So what is the solution on windows?
Generally the solution is to do something that looks like malware, or use a third party feature that side steps the problem, as happens with javascript.
