How to Use DriverStore Explorer (RAPR) to Clean Up Old Drivers
What it is
DriverStore Explorer (RAPR) is a free Windows utility that lists driver packages in the Windows driver store and lets you delete unused or outdated packages.
Preparations
- Backup: Create a System Restore point or full image.
- Download: Get the latest RAPR release from its GitHub releases page.
- Run as admin: Right‑click the executable and choose Run as administrator.
Step‑by‑step cleanup
- Refresh list: Click Scan to enumerate driver packages.
- Sort/filter: Use columns (Name, Class, Version, Date) to find old or duplicate drivers.
- Identify safe deletions:
- Prefer removing packages marked with multiple versions where one is much older.
- Avoid deleting drivers currently in use (RAPR shows a “In Use” indicator).
- Keep drivers signed by Microsoft unless you have a specific reason.
- Select packages: Check boxes next to packages you want to remove.
- Delete: Click Delete Driver Package and confirm. RAPR will attempt to remove the selected packages from the driver store.
- Reboot: Restart Windows after deletion to ensure stability.
Tips & cautions
- Do not remove “In Use” drivers. Deleting them can cause device failures or boot issues.
- Prioritize duplicates and very old versions. Leave the latest known‑good version.
- If unsure, export a list (use the app’s export or take screenshots) before deleting.
- Use Safe Mode if you encounter permission errors.
- Reinstall drivers from manufacturer if a device stops working after cleanup.
Troubleshooting
- Deletion fails: run RAPR as admin and disable security software temporarily.
- Device stopped working: reinstall the driver from Windows Update or manufacturer website, or roll back via Device Manager.
Quick checklist
- Backup created
- RAPR downloaded and run as admin
- Scanned, sorted, and marked only unused/old packages
- Deleted selected packages
- Rebooted and verified device functionality
