Hes actually right. Older Windows (<= 98 SE) had cooperative mutlitasking, so instead of everything being controlled by a kernel, apps were releasing system resources when they were programmed to instead being forced to by system. So instead of preemptive multitasking which looks like this:
OS: start app1
APP1: Printing hel
OS: now app2, you stop now app1
APP2: devran
OS: now app1 resume
APP1: ...lo world
OS: app1 finished. App2 now is your time
APP2: ...t is awesome
Cooperative mutlitasking was used which looks like this:
OS: goodapp1 start
GOOD: *running*
OS: good app I need to run now
GOOD: ok *good app is being baused*
OS: lets start bad app
BAD: Running...
OS: Can I run now plz
BAD: Nah m8 lmao
OS: Can I rum now
BAD: F*ck off
*OS freezes*
The only reason why we dont see this is because we are running CPUs with many GHz.
So yes, he was right, not today but around 18 years ago. -
@itsnameless Downgrades are fine too, since Linux Kernel was preemptive from its beginning (1991).

Root824797yDidn't you know, return adds two numbers together!
More seriously though, it's what @CopyPasteCode said. For Windows 3.11 and below, a program exiting would return control to the OS. (It was single threaded / no concept of threads). Thus, `return` would literally allow Windows to run again. -
@Ashkin nope, Win 98 SE and older (basically all DOS (pre NT) based Windows) - that means W98se, 98 and 95 too

Root824797y@CopyPasteCode I'm referencing the ones without any multitasking.
Though I could be wrong about this. I think I was 3 when I saw Windows 3.1 last... -
luguhe1777y@CopyPasteCode I know that he is right if he would have told this to me like 20 years ago but now we have multiple threads and multitasking is the main thing of a computer.

Last year in my first lesson of informatics:
Me: “What does return do?”
My teacher: “If you start your program, Windows will pause and run your program. If your program is coming to the end and hits the return statement, your program will stop and Windows will run again.”
wtf
(I already knew the right answer but I wanted to ask him this question.)
