InstallHotspotTask.ps1

A PowerShell setup script that configures Windows Mobile Hotspot to turn on automatically at every boot and stay on — even if it gets switched off unexpectedly.

---

What It Does

The script runs through 6 steps:

1. Sets execution policy — enables local scripts to run by setting RemoteSigned for the current user.
2. Prompts for hotspot credentials — asks for an SSID (network name) and a password (minimum 8 characters, validated interactively).
3. Generates HotspotKeepAlive.ps1 — writes a self-contained keepalive script to C:\Scripts\ that uses the Windows Runtime networking API to check the hotspot state every 30 seconds and re-enable it if it's found to be off.
4. Registers a Scheduled Task — creates a Windows Task Scheduler entry (HotspotKeepAlive) that runs the keepalive script at startup as the SYSTEM account with the highest privileges. The task runs indefinitely, restarts up to 3 times on failure (1-minute interval), and continues running on battery.
5. Starts the task immediately — kicks off the keepalive loop right away without requiring a reboot.
6. Reports status — confirms the task is running and displays the configured SSID and password.

Requirements

• Windows 10 or 11 with Mobile Hotspot capability
• PowerShell 5.1+ (built into Windows)
• Administrator privileges — required to register the Scheduled Task under the SYSTEM account

---

Usage

1. Right-click PowerShell and select Run as Administrator.
2. Navigate to the folder containing the script:

   cd C:\path\to\script

3. Run the installer:

   powershell -ExecutionPolicy Bypass -File .\InstallHotspotTask.ps1

4. Follow the prompts to enter your desired hotspot name and password.

That's it — the hotspot will now auto-enable on every boot.

Notes

• The generated HotspotKeepAlive.ps1 has your SSID and password embedded in plain text. Keep C:\Scripts\ access restricted if you're on a shared machine.
• The keepalive loop checks every 30 seconds. There may be a brief window after boot before the hotspot is confirmed active.
• If no active internet connection profile is found at check time, the script logs a message and retries on the next cycle.
• Re-running InstallHotspotTask.ps1 will overwrite the existing task and regenerate the keepalive script with new credentials.
