LicenseCrawler Tips: Securely Export and Store Your Product Keys

LicenseCrawler Guide: Recover, Backup, and Restore License Keys

Date: February 7, 2026

Recovering lost software license keys from a Windows PC can save time, money, and frustration. LicenseCrawler is a lightweight tool that scans the Windows registry to find product keys for installed software and system components. This guide shows how to use LicenseCrawler to recover keys, securely back them up, and restore them when needed.

What LicenseCrawler does

• Scans the registry to locate product keys and serials stored by applications and Windows components.
• Displays results in an easy list you can review, filter, and export.
• Supports many products, including Windows, Office, and common third-party apps.

Download and installation

1. Visit the official LicenseCrawler website or a reputable download site and download the latest portable ZIP.
2. Extract the ZIP to a folder — LicenseCrawler is portable and does not require installation.
3. Run LicenseCrawler.exe as an administrator (right-click → Run as administrator) to ensure full registry access.

Recovering license keys

1. Launch LicenseCrawler with administrative privileges.
2. In the main window, click the search button (or press F9) to start scanning the registry.
3. Wait for the scan to finish — results appear grouped by application and registry key.
4. Review the list; LicenseCrawler shows keys in a clear column labeled “Serial” or “Product Key.”
5. Use the search/filter box to find a specific product by name.

Backing up keys securely

1. Select the entries you want to back up (Ctrl+A to select all).
2. Click Export → Export to TXT (or CSV) to save a copy.
3. For added security, store the exported file in an encrypted container or password manager:
   • Create an encrypted ZIP using a strong password.
   • Or import keys into a reputable password manager that supports secure notes or file attachments.
4. Keep multiple backups: local encrypted copy + cloud backup in an encrypted form.

Restoring keys

• Software product keys are usually re-entered during reinstallation or activation. LicenseCrawler does not directly inject keys into installers, so restoring consists of:
  1. Reinstall the software or Windows as needed.
  2. When prompted for the product key, copy it from your secured backup and paste it into the activation dialog.
  3. If activation fails, check for product-specific activation steps (phone activation, online account linking).

Best practices and safety

• Run as administrator to ensure LicenseCrawler can access all registry locations.
• Verify source: download LicenseCrawler from its official site or trusted repositories to avoid tampered copies.
• Encrypt backups: never store keys in plain text on shared or cloud drives without encryption.
• Keep offline copies of critical keys for long-term recovery.
• Respect software licensing: use recovered keys only for legitimate activations and within license terms.

Troubleshooting

• No keys found: ensure you ran as administrator and that the software was previously installed on this Windows user/profile.
• Corrupt or unreadable entries: try exporting smaller selection groups or use alternative key-finder tools for comparison.
• False positives: cross-check suspicious entries against known product documentation.

Alternatives and complementary tools

• ProduKey (NirSoft) — small utility focusing on Microsoft product keys.
• Magical Jelly Bean Keyfinder — known for a simple interface and plugin support.
• Password managers — for long-term, secure storage of exported keys.

Quick checklist

• Run LicenseCrawler as admin → Scan → Export selected keys → Encrypt backup → Store offline and in encrypted cloud → Reuse keys during reinstall/activation.
