That was a terrible recommendation. Proposing a solution when you know nothing about the situation nearly always results in a pointless solution.

Suggesting that the best way to securely install Windows packages is to use a different operating system smacks of immaturity, and is obviously not a practical solution in Windows environments.

A better suggestion might be: If you do not trust it, run it in a VM/sandbox.

How is 'just ditch Windows' an honest and good recommendation?
