Windows Authentication - What Credentials Should I Use?

For VM/VMDR: Administrator privileges are recommended for the most accurate security assessment and recommended fixes for your system.

For PC/SCA: Administrator privileges (Build-in administrator or 'Domain Admins' groups member account) are required. The administrator privileges are required in order for the compliance scan engine to validate settings on the operating system.

Using an account with administrator privileges allows us to collect information based on registry keys, administrative file shares (such as C$) and running services. For VM/VMDR, it’s possible to use an account with less than administrator rights, however this limits scanning to fewer checks and scans will return less accurate, less complete results.
