# Get_Device_Info_V2.ps1
# ---------------------------------------------
# This script gathers system, hardware, network, and domain information
# from a Windows computer, saves the results to text and HTML files, and
# compresses them into a single .zip archive.
#
# Information collected includes:
#   - Group Policy results (gpresult)
#   - Hardware info (CPU, RAM, BIOS, Disks, GPU)
#   - Network configuration (ipconfig, route)
#   - Operating system details
#
# Usage:
#   - Run this script as a local administrator for best results.
#   - The output .zip file will be created in the same directory as the script.
#   - Temporary files are cleaned up after compression.
