What are these task manage processes?

[SwiftXShadow]

Imagine name/          User name/          Description

csrss.exe                   blank                    blank

winlogon.exe             blank                    blank

NvXDSync.exe          blank                    blank

nvvsvc.exe                blank                    blank

 

(blank as in it has nothing written in it)

 

If i try to force close them i get an error msg saying     access is denied

 

I read somewhere that these are actual windows files, but if that is so why is their description and user blank?

I looked another laptop that is the exact same one as this with the same windows, model, hardware, on that i could find winlogon.exe  that said it is a system file under user. So i tryed to force closing it, it let me, and as i realized force closing means a windows crash, which did happen.

 

Also the computer i have these blank user names and descriptions where i also cant close them, has a fresh windows install. Like 1 hour ago.

winlogon.exe I would assume to be the program that tells your computer who is using the computer so that it opens the right files and such

csrss.exe stands for client/server run-time subsystem. Its part of handling the windows system.

winlogon.exe is the user account system.

NvXDSync.exe is part of the Nvidia driver

nvvsvc.exe is also part of the Nvidia driver

 

None of these are procceses ment to be closed, as that would most likely crash the system

 

As to why you can see them on one PC and not another im not sure off. But either way its advised to just leave them be
