How to Protect USB Flash Drive with Windows 10?

If you have Windows 10 installed on your computer, ‘BitLocker,’ an encryption system integrated into the Microsoft operating system, allows you to protect the data contained in a USB flash drive in a few steps by encrypting it.

The first step you need to do is to connect the USB flash drive to a PC with Windows 10, then open the device window from ‘From This PC’ or ‘File Explorer’ and right-click on the drive icon assigned to USB.

Select ‘Enable BitLocker’ from the drop-down menu. Wait a while for the encryption processes to start and check the ‘Use password to unlock the unit’ option from the first window that opens. Type a password in the field below and click the ‘Next’ button. In the next window, you choose how to back up the required recovery key to access the encrypted data on the USB drive. Select the ‘Save to a file’ option and press ‘Next.’

If you want to use it on other PCs in different places where you sign in with your Microsoft account, select ‘Save in Microsoft account’ and continue with the actions prompted. In the window that opens, select ‘Save to file’ and choose the path where you want to save the file with the encrypted key. Finally, click the ‘Save’ button and then click ‘Next.’

In the next window, you must decide to encrypt a portion of the USB flash drive and check the ‘Apply encryption only to the used area of ​​the disk’ option or the ‘Encrypt the entire drive’ option to encrypt the available space. You must select the encryption compatibility level; we recommend leaving ‘Compatible mode’ checked to decrypt data on other devices. Finally, select Next> Start encryption to start the encryption processes of the entire drive.

After enabling BitLocker encryption on the USB key to access its contents, you will naturally prompt to type in the password you set beforehand. If you don’t order the correct password, you cannot access or change the files on the USB device.

If you think about it and want to remove BitLocker encryption, open the ‘File Explorer’ window and right-click on the drive icon assigned to the USB drive. Then select ‘BitLocker Management’ from the menu that appears.

In the window that opens, confirm ‘Disable BitLocker’ at the bottom and then confirm the warning that appears. Finally, wait for the encryption removal procedure to complete. Even in this case, it takes a few minutes.

When USB BitLocker encryption is finished and disabled, you can access its contents without typing any password.
