Block USB drives.
Unlock them with a password.
LockUSB stops USB sticks, external disks, phones, memory cards and DVDs from working on a Windows PC. When someone plugs one in, a password window appears. The right password allows that device for as long as you choose, then it locks again on its own.

LockUSB–□×What people see when they plug in a USB drive.
Stop data walking out, and viruses walking in
LockUSB uses Windows' own device policies, so it's light, reliable, and keeps working after restarts.
Blocks all USB storage
USB sticks, external hard disks and SSDs, and phones and cameras that connect as storage. Keyboards, mice, printers and webcams keep working.
Memory cards and DVDs too
SD cards in USB readers and in the PC's own card slot, and CD/DVD drives, reading and burning. Card readers stay quiet; only an inserted card asks for the password.
Password to unlock
Plugging in a device opens the password window. Allow just that device, or every USB device, for 5 minutes up to 30 days, or always.
Locks again by itself
When the time is up, the device is locked again, with a warning two minutes before so people can save their work.
Hard to get around
Standard users can't stop it or change its files. The password is checked by a protected Windows service, and after 5 wrong tries it pauses for 5 minutes. It stays active in Safe Mode.
Logged and easy to roll out
Every unlock and wrong password goes to the Windows Event Log. Install silently on many PCs with Intune, PDQ, SCCM or Group Policy.
Set up in two minutes
Install
Run the setup as an administrator and choose the unlock password. USB storage is locked straight away.
Someone plugs in a drive
Instead of the drive opening, LockUSB asks for the password. Without it, the drive stays locked.
Unlock when you need to
Enter the password and pick how long. The padlock in the taskbar shows what's allowed and lets you lock everything again.

Need an invoice, a purchase order or more than 1,000 PCs? Email [email protected]. Payments are handled by Paddle, our reseller, which issues tax invoices and accepts cards, PayPal and more.
Deploy to many PCs
The setup runs silently, so you can push it with Intune, PDQ Deploy, SCCM or a Group Policy startup script.
LockUSBSetup.exe /VERYSILENT /SUPPRESSMSGBOXES /PASSWORD="your-password" /LICENSE="LOCK-XXXXX-XXXXX-XXXXX-XXXXX"
To keep the password out of your deployment tool, set LockUSB up on one PC, export the password hash, and deploy with that instead:
"C:\Program Files\LockUSB\LockUSBService.exe" exporthash LockUSBSetup.exe /VERYSILENT /SUPPRESSMSGBOXES /HASH="<salt>:<hash>" /LICENSE="..."
One key covers all the PCs you bought. Silent uninstall: "C:\Program Files\LockUSB\unins000.exe" /VERYSILENT
Questions
Which versions of Windows does it work on?
Windows 10 version 2004 or later and Windows 11, 64-bit. Older versions of Windows 10 lack features LockUSB relies on. Use the free trial to check it on your PCs before buying.
Does it block keyboards, mice or printers?
No. Only storage is blocked: USB drives and disks, phones and cameras in file-transfer mode, memory cards and CD/DVD drives. Everything else works as normal.
Can a student or employee get around it?
Not with a standard Windows account. LockUSB runs as a protected Windows service that standard users can't stop, and its files and settings can't be changed without administrator rights. People with administrator rights can always remove software, so give users standard accounts.
What happens after the 7-day trial?
LockUSB stops blocking and shows a notice. It never leaves you locked out. Enter a license key and protection starts again straight away, with your password and settings as they were.
How do I move my license to a new PC?
On the old PC, right-click the LockUSB padlock, choose License… and then Remove license. Then enter the key on the new PC. If the old PC is broken or gone, email us and we'll free it up. Reinstalling Windows on the same PC doesn't use up another PC.
I forgot the password.
Anyone with Windows administrator rights can set a new one: run the LockUSB setup again and enter a new password, or run "C:\Program Files\LockUSB\LockUSBService.exe" setpassword from an administrator command prompt.
Does LockUSB need the internet?
Only to activate a license key, and for a short license check once a day. Blocking and unlocking work offline. If the check can't reach us, nothing changes.
Does it send my data anywhere?
No files or device contents ever leave the PC. The license check sends only the license key, an anonymous ID made from the PC's hardware, and the PC's name. See the privacy policy.
What if I'm not happy with it?
Email [email protected] within 14 days of buying for a full refund. See the refund policy.
Windows warns about the download.
Windows SmartScreen can warn about new downloads until they're widely used. Download LockUSB only from lockusb.com. If you see the warning, choose More info and then Run anyway.
