Generally speaking, those applications installed on your computer that run in the background can be closed, while those service programs/processes that run automatically in Windows cannot be closed (can be found in the description column of the process).However, this does not mean that all applications/processes running in the background (the software you installed) can be closed, such as Xunlei's data transmission channel, anti-virus software's background protection program, etc.There are also some processes, such as sound cards.In fact, if you want to close a background program to release memory, you can use the memory release tool provided with the anti-virus software. Generally speaking, you should not close the background process directly through the task manager. This may cause the computer to crash, or you may lose the data of the applications you closed.
