Why is "Windows server" doing in my MacOS

Hi

I want to know why is WindowServer process running in my MacOS 10.15.6 and occupy nearly 40% of CPU time? Is WindowServer refers to Microsoft Windows Server? Although I do not feel the sluggishness but I do not feel "good" about it.

Am I compromised for "crypto-mining" malware or something?

Kindly advise the necessary. Thank you.

Regards,

James
