phpstudy's php-cgi.exe occupies resources and database permissions issues

Question

Question 1:

After installing phpstudy, there are many php-cgi.exe processes and the CPU usage is always 100%. Ignore the security dog ​​and computer manager. Before installing these two security software, It has always been like this.

Question 2: There is no place to set phpstudy, website permissions, and database permissions?

Have you tried other integrated environment software before, different websites, different user permissions, phpstudy, do they all default to one, or does it have super administrator permissions?

#In addition, the security dog ​​as shown below cannot set the database permissions?
