How to View and Remove USB Connection History on Your PC
See which USB drives have been connected and clear that history for privacy — on a PC you own.
Overview
Windows keeps a record of USB devices ever connected. You may want to view this for troubleshooting or clear it for privacy. This guide shows how, on a computer you own or administer.
Viewing and removing USB connection history.
Note: Only view or clear USB history on a computer you own or are authorized to manage. Clearing device history is a privacy/maintenance task, not a way to hide activity on someone else’s system.
Key Takeaways
- Windows logs connected USB devices in the Registry.
- You can view the history with a tool like USBDeview.
- Clearing entries removes the stored device records.
- Back up the Registry before editing it manually.
View USB History
1. Registry: open regedit and browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR to see past devices.
2. Or use NirSoft USBDeview (official site) for a friendly list with dates.
3. Note the devices and connection times if troubleshooting.

Remove USB History
Warning: Editing the Registry incorrectly can cause problems. Back up the Registry first.
1. With USBDeview, select entries and uninstall/remove them.
2. Or, in regedit, delete specific device subkeys under USBSTOR (carefully).
3. A dedicated cleaner tool (e.g., USBOblivion, from its official source) can clear USB traces in bulk.
4. Reboot to finalize.
Troubleshooting
Problem: Access denied deleting a key.
Solution: Run regedit as administrator; some USBSTOR keys need ownership/permission changes.
Problem: Device reappears after reconnecting.
Solution: History is recreated when you plug the device in again — that’s expected.
Problem: Tool flagged by antivirus.
Solution: USB-trace cleaners are sometimes false-flagged — download only from the official source and verify.
Problem: Not sure which key is which.
Solution: Use USBDeview, which labels devices clearly, instead of editing the Registry blind.
Conclusion
Windows records connected USB drives under USBSTOR in the Registry. View them with USBDeview, and clear entries with a trusted tool or careful Registry edits — after backing up — on a PC you own. Remember the history simply rebuilds when devices are reconnected.
