# remove-sagex-windows.ps1 — leave only the Mango wallet and the official Sage wallet.
#
# Run in an ordinary (not administrator) PowerShell, AFTER opening the new Mango wallet once:
#   powershell -ExecutionPolicy Bypass -File .\remove-sagex-windows.ps1
#
# What it does, and what it never does:
#   * finds SageX by its uninstall entry (DisplayName "SageX"), stops only processes running
#     from SageX's own install folder, and runs SageX's own uninstaller silently;
#   * MOVES (never deletes) every SageX data folder — com.web3utxos.sagex and net.namid.sagex,
#     under Roaming and Local AppData — into %USERPROFILE%\SageX-backup-<date>\, and only after
#     checking that Mango holds a copy of the same keys.bin. Your recovery phrase still opens
#     everything; this folder is a second copy you can delete yourself later;
#   * moves SageX Start-menu and Desktop shortcuts into the same backup folder;
#   * never touches the official Sage wallet (com.rigidnetwork.sage) or Mango (net.namid.mango).
