# kms-bootstrap.ps1
#
# Interactive KMS activator. Asks what you want to activate (Windows /
# already-installed Office / Project / Visio) and runs only what you confirm.
# Points each product at the public KMS host (default: vlmcs.viktorbarzin.me:1688).
# When a Volume License key is missing it auto-detects the edition/product and
# fetches the matching GVLK from the published key list (no manual key lookup).
#
# Usage:
#   iwr -UseBasicParsing https://kms.viktorbarzin.me/scripts/kms-bootstrap.ps1 | iex
#
# Non-interactive (CI / automation):
#   $env:KMS_AUTO = 'win,office'; iwr ... | iex
#       (comma list of: win, office, project, visio)
#
# Custom KMS host:
#   $env:KMS_HOST = 'kms.example.com'; iwr ... | iex
#
# Source: https://kms.viktorbarzin.me/scripts/kms-bootstrap.ps1
# Licence: MIT, no warranty, KMS activates Volume License SKUs only.
