convince me

tell me why I would want to switch to using windows.

why would I want to become vulnerable to 100% of viruses, 100% of exploits?
why would I want to become at the mercy of one company, that has no vested interest in keeping my business a going concern?
( I know linux and apple don’t either, but linux at least wants compatability, and tries to address issues [ apple is as bad with macs as ms is with windows for proprietary ] )

what does windows offer that cannot be met with linux?

this is an opportunity for you to sell windows, go for it.
