How do I monitor the entire system and capture active window switching events?

Want to achieve the following functions:

The system runs as a background process and monitors the operating system. When the active window is switched (for example, from word to ie), a new thread is triggered to handle the corresponding transaction.

Excuse me, what is the best way to achieve this? Can I list key functions? It is best to explain why this is better than other methods!

I only know how to do this, and I am studying hard. Is there any other way? Isn't it that hooks take up more resources?

It is not possible to implement global hooks in the Microsoft .NET framework. To install a global hook, the hook must have a native dynamic link library (DLL) exported in order to insert itself into another process that needs to call into a valid and consistent function. This requires a DLL export, and the .NET framework does not support this. Managed code does not have the concept of function pointers having uniform values, because these functions are dynamically constructed proxies.
