bloatware

Bloatware is a term for unwanted [ and unnecessary ]pre-installed software on a computer or device. Source: TechTarget

For example…

New computers…

…especially those with the Windows operating system…

…may ship with a free trial of third party antivirus software…

…at the end of the free trial period you have to pay in order to keep using the virus protection software.

Many people (in your Tech Wizard friend’s experience) think this third party virus protection software is their device’s only virus protection, so they pay to continue using it đź’°

But the Microsoft Windows operating system has its own built-in security which was created by Microsoft engineers — and it’s free 🤷‍♂️

a poke is a slang term for a bag

“A pig in a poke” and “don’t let the cat out of the bag” both stem from the same source: a common early 20th century con. If you go to a county fair to sell piglets, you can easily take advantage of people who are not suitably suspicious.
