Every Computer Myth You Still Believe Explained in 30 Minutes

That computer advice you trust most? It was probably true — in 2004. The hardware changed underneath it, and nobody sent you the update.
We bust 18 computer myths in plain English, and reveal that almost all of them were once genuinely good advice that simply expired — plus one that was never true and only exists to take your money. You'll learn why you can pull a USB stick straight out, why charging overnight doesn't kill your battery (heat and hours at 100% do), why "add more RAM" only helps if you're actually short — with a 30-second Task Manager test — and why defragmenting an SSD wears it out instead of helping. We cover the truth about Macs and viruses (protect the account, not the OS), what Incognito really hides, why Windows Defender is now enough for most people, and the numbers on the box that quietly cost you money: the "1ms" monitor label physics doesn't allow, megapixels, and the 80 Plus badge. It ends with the one myth that was never real — PC cleaners and registry optimizers — and the five free things actually worth doing tonight.
