WindowsUpdateRestartAutomater

A PowerShell automation that installs pending Windows updates unattended, logs the whole process, and schedules an automatic restart when one is required — intended to run overnight via the Windows Task Scheduler.

Features

• Checks for an internet connection before starting.
• Installs the PSWindowsUpdate module automatically if it is missing.
• Enables the Microsoft Update service and triggers an update scan (usoclient).
• Downloads and installs available updates, writing a timestamped log to %SystemDrive%\UpdateLog.txt.
• If a reboot is needed, schedules a restart via schtasks (e.g. during the night).
• A .bat launcher runs the script with -ExecutionPolicy Bypass.

Files

• autoUpdater.ps1 — the main update-and-restart script.
• updateRestartAutomater.bat — launcher that runs the script from %USERPROFILE%\Documents\.

Tech

• Windows PowerShell, the PSWindowsUpdate module, and schtasks / usoclient.

Usage

Place autoUpdater.ps1 in your Documents folder and run the launcher as an administrator, or run the script directly:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
powershell -NoProfile -ExecutionPolicy Bypass -File autoUpdater.ps1

For unattended operation, register it as a scheduled task (for example at 02:00). Requires administrator rights.
