FIX: Cannot Reset Surface Pro 4 Drive is Locked with BitLocker (Solved)

Recently one of my customers brought to me his Surface Pro 4 tablet because he cannot reset Windows 10 to the default factory settings from the Recovery Options. In fact, after the user chooses the "Reset This PC" option, he is asked to enter the recovery key (BitLocker Drive Encryption key) to unlock the drive. But, in his related Microsoft account, there is no any saved any "Bit Locker" key for his Surface 4 Pro tablet and as result of that issue, the "Reset This PC" option can continue.

Additionally, the problem becomes bigger, because if the user chooses the "Skip this drive" option, the operation ends with the following error: "The drive where Windows is installed is locked. Unlock the drive and try again".

If you don’t have a Windows Installation Media then you can create one by using Microsoft’s Media Creation tool.
