Since I need to debug and test older Windows when I recode software I set up a custom rolled Windows 8 that has no MS bloat, the bare minimum of MS system files to run and custom system software I coded with a custom security suite and on a virtual machine sandboxed separately from the host OS. I don't even use the real OS and the virtual one is a sandbox in a sandbox. Everything is firewalled and proxied the only thing that can access the Internet freely is Waterfox and it's sandboxed over a sandboxed host proxy. Hard to explain what it is, you dawg I heard you like Internet so I put Internet in your OS so you can Internet when you OS.

Not just secure but stealth, I leave no trace or fingerprints.
