Properly secured Windows (except Windows10) computer is unbreakable. Even for NSA. Why? Because a 0-day in network stack or network card drivers is only way to hack it. Manually install all security patches. Disable all auto updates. Disable unnecessary services and configure firewall to reduce attack surface. It is it. I challenged to hack my Windows 7 or Windows XP machine to steal all my coins back then. Nobody succeeded. In such case the NSA/CIA/FBI will try to get physical access to machine to install malware or read disk contents.
It is ridiculous how paranoid some Windows haters are. They obviously never been hackers themselves and also dont know how police and spy agencies do things.
More notable thing that probably nobody noticed is that Satoshi's hard drive was using NTFS compression, most likely on whole partition. This is very untypical to have NTFS compression enabled on whole partition upon manual formatting.
Doesn't make sense to me. In order to be sure that something is not hacked, you would need to at least know what the code is doing. Sure this doesn't mean that Linux isn't hackable, everything with code is, but my point is.. how do you even know what updates to enable and what other updates to ignore? Updates are packages of closed source code. You are trusting to believe what it says on the description but you don't know what you are actually installing with each update, one of these updates could contain a backdoor for the NSA or something. You can block ports with a firewall, but that's about it. A keylogger that's embedded in a file that is part of the OS would go ignored by firewalls for instance. For example, imagine that the reporting tool in windows which is just an exe, sends a text file with keystrokes to someone... how would you even notice if you can't see what Dw20.exe is doing? (or any other closed source executable for that matter).
