Requirements

• Windows 11
• PowerShell 5.1+ (or PowerShell 7)
• Run as Administrator

Usage

Quick Start

Simply double-click MSStoreRepair.ps1 or run from PowerShell:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
.\MSStoreRepair.ps1

The script will:

1. Auto-detect if running in STA mode (required for WPF) and relaunch if needed
2. Check for Administrator privileges and prompt to elevate if needed
3. Launch the GUI interface

Logs

Daily log files are automatically created in:

.\logs\msstore-repair_YYYY-MM-DD.log

Log format:

[2026-01-10 15:30:45] [Info] Starting: Diagnostics
[2026-01-10 15:30:46] [Success] Operation completed
[2026-01-10 15:30:47] [Warning] Service not found
[2026-01-10 15:30:48] [Error] Failed to execute

Troubleshooting

• Appx cmdlets not available: Use Windows PowerShell 5.1 instead of PowerShell 7, or import the module:

  Import-Module Appx -UseWindowsPowerShell

• Operation timeout: wsreset.exe has a 60-second timeout to prevent hanging
• Check logs: All operations are logged with detailed error messages
