Hello，

It sounds like you’re encountering a situation where the Windows Installer (msiexec) is repeatedly launching, showing its help/usage text or similar pop‐up dialog. This kind of behavior often indicates that something—whether a system update, a scheduled installation, or even a misbehaving third‑party application—is triggering the installer service in an unexpected or corrupted way. Here are some troubleshooting steps you can try:

1. Check for Pending or Stuck Installations or Updates

 • Sometimes a Windows update or another application installation isn’t completing as it should, causing Windows Installer to repeatedly launch.

 • Open Windows Update (or your update tool) and look for any pending downloads or error messages.

 • Check the “Programs and Features” list in the Control Panel to see if any application appears to be mid‑installation or “advertised” without having properly installed.

2. Examine Event Viewer Logs

 • Open Event Viewer (type Event Viewer in the Start menu and open it).

 • Look under Windows Logs → Application for entries from “MsiInstaller.”

 • The logs might provide clues as to which product or update is causing the issue.

3. Unregister and Reregister the Windows Installer Service

 • Corruption in the Windows Installer configuration can sometimes cause repeated pop-ups.

 • Open an elevated Command Prompt (right‑click Command Prompt and choose “Run as administrator”).

 • Type the following commands one at a time and press Enter after each:

   msiexec /unregister

   msiexec /regserver

 • This process will unregister and then reregister the Windows Installer service. Reboot your computer afterward to see if the issue is resolved.

4. Scan for Corrupted System Files

 • Run the System File Checker to fix potential system file issues that might be affecting Windows Installer.

 • Open an elevated Command Prompt and type:

   sfc /scannow

 • Wait for the process to finish and follow any instructions, then restart your computer.

5. Check Startup Items and Scheduled Tasks

 • Sometimes an application scheduled to run at startup (or as a scheduled task) may be triggering an installation repeatedly.

 • Use Task Manager (Startup tab) or search for “Task Scheduler” and review tasks that might be related to installations or updates.

 • Disable any suspicious or unnecessary tasks temporarily to test if the behavior stops.

6. Clean Boot

 • Perform a Clean Boot to start Windows with only essential services. This can help determine if a third‑party software or service is causing the problem.

 • Search for “msconfig” in the Start menu, open System Configuration, and under the “Services” tab, check “Hide all Microsoft services” then click “Disable all.” Also, disable startup items and restart.

 • If the issue stops in a clean boot environment, re‑enable items one by one to pinpoint the culprit.

7. Update or Repair the Application Triggering the Installer

 • If you identify a specific application that seems to be initiating Windows Installer (via logs or by noticing which software recently failed to install/update), consider repairing or reinstalling that application.
