How to check CPU temperature in Windows 8, 7, Vista, XP and Ubuntu?

On desktop it is quite hard to have a good temperature assumption so you cannot have a clear opinion about your system's temperature. Therefore, it is clear a user will have no idea if his/her system is overheating or not. On Laptops, you can have a clear assumption whenever your system overheats.

So let's kill our assumption with some hardware monitoring applications.
