How can windows task manager close frozen program which we cant by clicking on close button?

“Close program” – a polite request that the program stop doing what it’s doing as soon as it’s done.
“End process” – I wasn’t asking.

It is the difference between politely asking someone to please leave and having security drag them out.
The former takes longer and involves cooperation of the individual the latter works every time even if they don’t cooperate but is a lot messier.
Asking the program to please close only works if the program hears you and isn’t busy with other stuff. Externally killing the process is brutal and leaves a mess, but it works even if the program is too busy to listen to you asking it to please stop.

Different calls:
– clicking ‘close’ asks the program “please close”
– selecting ‘end task’ in task manager, asks scheduler/kernel to close application (Boss angrily asks application to close)
– using kernel call “taskkill /f /im explorer.exe” is an example of a kernel ‘force close’ command for an app. (boss kicks application out)
– pushing and releasing the power button – OS level request to shutdown gracefully (Building closing – follow exit signs)
– holding power button in for 8 seconds – motherboard halt and shut down command
– pulling power and battery – no power can’t run
This is kind of like a mechanic:
– use a wrench
– use a breaker bar
– use a torch to melt it off (can’t be stuck if it’s a liquid)

The trick is the task manager just kills exactly the task you ask it to. On some CAD and analysis software I use other subcomponents often are still left running meaning I have to still power cycle the PC to rerun the program if I don’t know all the tasks that must be individually killed. And if a swap file is being accessed at that moment your work so far is often corrupted. The task manager really is a last resort for me.

Hitting the close button is like asking someone to get off a ladder. If they’re frozen because they’re scared of heights, they may not respond to you.
Hitting ‘end process’ in Task Manager is like pushing the ladder over to get them off it. It works, but it may have negative consequences for the person on the ladder.
Think of it like a kitchen.
When the program is running, the chef is cooking, dishes and food get moved around. When you close the program normally, the chef cleans up and outs everything back where it’s supposed to be. When you close it with task manager, you just dump the entire mess in the trash and call the kitchen clean.
Properly closing the program ensures that any data is saved properly and any routines running in the background end properly, but when you end the task in task manager, it stops everything right then and there, so there may be incomplete data or it could have been in the middle of a loop, but all of that is just thrown out instead of being allowed to complete.
