Do people not recall that XP, even after SP3, was the OS of over a decade of botnets, ransomware, and worms that crippled the web? Even Vista and 7 were guilty if you were lax and disabled UAC.

All of the things people are complaining about here, like Microsoft becoming the de facto admin of of their Desktop Windows 10 products, are direct results of a period they manufactured.

All anyone who waxes nostalgic should do to test is install anything earlier than 10 on an internet facing computer and then wait. It's terrifying how fast they get compromised.
