Bootstrap installer for the AD User Tool (private repo). Downloads the latest release from GitHub using OAuth Device Flow authentication.

Paste in PowerShell 7:

irm https://raw.githubusercontent.com/seanGSISG/UserTool-Installer/main/Install-ADUserTool.ps1 | iex

1. First run — A browser opens to https://github.com/login/device. Sign in with your GitHub account and enter the code shown in the terminal (auto-copied to clipboard).
2. Download — The latest release zip is downloaded from gsisg-inc/UserTool and extracted to C:\IT\UserTool.
3. Setup — Dependencies are installed (gsudo, RSAT AD tools, Microsoft Graph modules) and a Windows Terminal profile is configured.
4. Future runs — Your token is cached in Windows Credential Manager. The installer checks the version and only updates when a new release is available.

• PowerShell 7+ — Download
• GitHub account with access to the gsisg-inc organization

If authentication fails or your token has expired:

cmdkey /delete:UserTool:GitHub:DeviceFlow

Then re-run the install command.

Your GitHub account must be a member of the gsisg-inc org. Contact an org admin to confirm your membership.
