.SYNOPSIS
  Get-SystemReport - prints a one-screen system report for Windows.

.DESCRIPTION
  READ-ONLY. Reports OS build, CPU, memory, fixed disks and IPv4 addresses.
  Writes to the console only. Nothing is modified, nothing is uploaded.
  Needs no administrator rights.

.EXAMPLE
  powershell -ExecutionPolicy Bypass -File .\Get-SystemReport.ps1
