The laptops we purchased to be dedicated Bitcoin wallets are HP. HP is in the news for having shipped computers with keyloggers pre-installed. It turns out that the microphone tray applet for the sound card drivers shipped with these computers happened to be logging every single keystroke to a unencrypted unprotected file. It turns out that this is only the case with the windows drivers and software. If windows is removed and is completely replaced by x a boon to, as is in our case, this vulnerability simply does not exist.
The reason we replaced windows for exhibition to is that 100% of the software is open source and the source code is visible and available for inspection. That also applies to the sound card, WiFi, keyboard, and all other drivers and software on the system. Given this latest incident from HP and Microsoft, I’m not sure how I could ever trust a Windows system ever again for critical Computing tasks. It frightens me to no end that critical medical devices and Fire Control Systems on US Naval warships both run Windows.
