Windows 7 system function for U disk encryption

Now, when you choose a mobile storage device, everyone will choose a USB flash drive, and its capacity has evolved from an inconspicuous appearance to a capacity of tens of G. However, because of its convenience, many people did not set a password for it, resulting in the loss of data. In fact, setting passwords is not that much trouble. Xiaobian found that the windows7 system has a function to encrypt our U disk, the following small series will be demonstrated. Before we start the BitLocker security feature of Windows 7, we need to log in to the Windows 7 system as an administrator before it can be used. In view of many netizens, it is not clear how to log in to the system as an administrator. Let's start with a demonstration. If you know you can skip this part. Log in to the system as an administrator. First, click on the “Start” menu. In the “All Programs” section, find “Additional” and click on “Command Prompt”. In the second step, enter the following command: <;net user administrator /active:yes” Then log out or restart the system to use the super administrator account. In particular, the spaces here are all three, so to enter it is to press the space bar three times. Of course, if you decide not to use the super administrator account in the future, the operation steps are the same as above, just replace the input command with “yes” with “no”. The Windows 7 system function is the first step of encrypting the USB flash drive. In the “Computer” interface, right click on the USB flash drive that requires the password, provided that the USB flash drive has a certain storage space. Select “Enable BitLocker…” from the context menu. The second step, starting up takes a little time. In the “BitLocker Drive Encryption” interface, select “Use password to unlock the drive”, and then you need to enter the password twice in succession. The password here needs 8 characters, which means you need to enter 8 letters or numbers. Click “Next”. The third step, "BitLocker" interface will prompt to create a recovery key to save to a file or print retention, this proposal is kept in the file to prevent forgetting the password. You will get a text file with the name "BitLocker recovery key ***.txt", which you can use later to retrieve the password. In the fourth step, you can click “Start Encryption” and BitLocker will start encrypting your U disk. It takes a little time depending on the file size. In this way, our U disk has been "locked", and only after the password is correctly entered, the U disk can be used normally, and the privacy can be well preserved. Postscript: U disk is not only available in Windows 7 system, but also in XP system. However, the XP system can open the USB flash drive, but the files inside still need to be correctly entered to open.
