If you have a Bitlocker drive in your Windows 10 computer, you may have noticed that it is not unlocking anymore. This is because the drive has been locked by the manufacturer. To relock the Bitlocker drive, you will need to use a different method than what you used to unlock it. To relock the Bitlocker drive in Windows 10, first open the Start menu and type “cmd” into the search bar. Then click on “cmd” and then click on “run as administrator.” This will open a new window that will ask for your administrator password. After entering your administrator password, click on “OK.” Now, open the command prompt and type “relockbitlocker.” This will start the Bitlocker lock process. After it finishes, your Bitlocker drive will be unlocked again.
