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.
