PowerShell - summary system report

I present to you a PowerShell script that uses can be useful for monitoring system resources and checking the current configuration. The script saves the data in a table and generates a diagnostic report, which is useful for administering larger environments or analyzing problems.

This script does:

CPU and RAM monitoring
Analysis of free disk space.
Verification of accounts and accesses
Scanning open network ports.
Checking security policies
