Use a Windows PC to Password Protect Your Flash Drive
Windows computers allow you to encrypt your flash drive by using a built-in program called BitLocker. Windows 7 Enterprise, Windows 10 Enterprise, Windows 7 Ultimate, and Windows 10 Pro all come with this software.
You should know that you can unlock and lock thumb drives between Windows 7 and Windows 10 computers. It is not possible, however, to interchange with an OS operating system. Use the steps below to start the encryption process.
1. Open Windows Explorer.
2. Right-click on the appropriate drive.

3. Press “Turn on Bitlocker.”
4. Check the box labeled “use a password to unlock the device.”

5. Type in the password you want to use twice.
6. Select the option for how you want to save the recovery key. (Print, save to your account, save in a file)

7. Choose if you only want to encrypt the disk space or the whole drive.
8. Press “start encrypting.”

Next time you plug the USB device into your computer, you will have to enter the password you chose. Bitlocker does allow you to select devices in which you automatically unlock the flash drive.
BitLocker Requirements
To use BitLocker on your computer, there are more requirements to consider. It cannot simply be a Windows computer. Other necessities include:
- TPM 1.2 or higher computers
- TCG-Compliant BIOS firmware or TCG-Compliant UEFI firmware
- Firmware has support for Static Root of Trust Measurement
- Support for a USB mass storage class
- Two drives on the hard disk
- NTFS file system on the operating system drive
- Non-encrypted system drive
- FAT32 file system with UEFI firmware and NTFS file system with BIOS firmware
- Recommendation of a 350 MB system drive
- Installation of the Enhanced Storage feature
If you have a Windows computer, but it does not meet these requirements, you cannot use Bitlocker. You still have options, however.
