Do you realize that what microsoft did with win10 (full botnet and keylogger) is actually raising legitimacy and security of old windows?
I always expected and was scared that old windowses might already have some hidden microsoft backdoors, botnets, and they might hide from your packet sniffers (run on win OS) etc
But when microsoft actually wanted to implement full botnet they didn't hide that. And it makes sense, if you hid that and it would eventually be discovered and become public it would be huge, they could be destroyed by public and by lawsuit. So what did they do instead? Simply, insert full backdoors and prison cage but call them a "feature" and include in EULA. I noticed same thing from other jewish zionist companies like Google, Intel, Facebook etc. For example, Google doesn't hide the fact that it records your GPS position with android, your WIFI ssid/position/password, your browsing history etc. Instead they call it "feature" and stupid goys believe them. Also, the backdoor in Microsoft's BitLocker encryption also isn't hidden, it's just called a feature.
Only sometimes do jewish companies hide their actions, like was in case of Google which was recording unencrypted wifi data with their google cars. But when somebody realized that and blackmailed them, they did damage control by admitting this to public.
So the most secure OS is old windows. Linox is crap made by amateurs (latest tcp backdoor, heartbleed etc prove that). There is no longer a single point in using lanix, because security was last thing that was believed to be better than windows.
