Small business still running Windows 7... Obviously EOL. Only really use Office 2003 (heh), Chrome (EOL on Win7), and some kinda Panda Antivirus that uses 2-3 MEGABYTES per second of network traffic and features a spinning bear icon that makes the owner feel safe.

"I don't want to replace anything that's working."

No ransomware notes on desktops, though. So...
