  • Registry Scanning - Scans all uninstall registry keys:
    • HKEY_LOCAL_MACHINE (64-bit applications)
    • HKEY_LOCAL_MACHINE\WOW6432Node (32-bit applications)
    • HKEY_CURRENT_USER (user-installed applications)
  • Microsoft Store Apps - Detects UWP/AppX packages via PowerShell
  • Program Files Scanning - Finds unregistered applications in Program Files directories
  • Winget Cross-Reference - Populates Winget IDs for registry apps (enables one-command reinstall exports)

Detailed Information Captured

  • Application name
  • Publisher/vendor
  • Version number
  • Installation date
  • Installation location (disk path)
  • Registry uninstall key path
  • Uninstall command
  • Estimated size
  • Architecture (32-bit/64-bit/UWP)
  • Application type (Desktop/Store/Unregistered)
  • Winget Package ID (when matched)

Premium Interface

  • Dark theme with professional aesthetics
  • Dark Windows title bar integration
  • Real-time progress tracking
  • Statistics dashboard with card widgets
  • Sortable columns (click headers) — Name, Publisher, Version, Date, Location, Registry Key, Type, Size, Arch, Winget ID
  • Live search filtering
  • Category filtering (Desktop/Store/Unregistered)
  • Context menu with quick actions

Export Options

  • TXT Export - Formatted report with full details
  • CSV Export - Spreadsheet-compatible for Excel/Google Sheets (includes Winget ID column)
  • Markdown Export - Grouped report (Desktop / Store / Unregistered) — pastes cleanly into ticketing systems and GitHub
  • JSON Export - Full AppList schema, round-trippable for diffing between machines

Installation

Or double-click AppList.py in Windows Explorer.

Usage

  1. Launch the application
  2. Click "Scan System" to begin comprehensive scanning
  3. Use the search bar to find specific applications
  4. Use the filter dropdown to show only certain types
  5. Click column headers to sort
  6. Right-click any item for context menu options
  7. Double-click to open the install location
  8. Export your list as TXT, CSV, Markdown, or JSON

Export Formats

TXT Format

Human-readable report with:

  • Header with generation timestamp
  • Numbered list of all applications
  • Full details for each application
  • Professional formatting

CSV Format

Spreadsheet-ready with columns:

  • Application Name, Publisher, Version, Install Date
  • Install Location, Registry Key, Uninstall Command
  • Estimated Size, Source, Architecture, Type, Winget ID

Markdown Format

GitHub-ready grouped report:

  3. The Winget ID column shows which apps can be reinstalled with winget install <ID>
  4. Use the CSV in Excel to mark off apps as you reinstall them
  5. Note the install locations - some apps may need special paths

Technical Notes

  • Runs with elevated privileges for complete registry access
  • Automatically filters out:
    • System components
    • Windows updates
    • Framework packages
    • Duplicate entries
  • DPI-aware for sharp rendering on high-resolution displays
