    Win 8.1 Upgrade: Bitlocker Encryption Control App Missing


    Hello all, my issue first originates with going through the windows 8.1 store app to upgrade windows 8 -> to windows 8.1.

    "turn off bitlocker because it isn't supported in the edition of windows you want to install"

    I am not sure whether i encrypted the drives after installing windows 8 or in windows 7, nevertheless i do know the encryption passwords to the drives.

    The biggest problem is therefore trying to remove/disable the encryption to upgrade.
    The Applet in the control panel is missing for some reason and so I ask for help here.
    I have seen some guides which rely on this applet which is usually situated between auto play and colour management.

    I would like to remove/disable the encryption for the upgrade, or confirm the idea that if i disconnect the two drives that are encrypted i could upgrade the OS to 8.1 and wouldn't need to worry about the encryption.
    The concern is that the 8.1 OS would not read the drives hence the upgrading message.

    My specs are this , related to Bitlocker:
    • Windows 8 64bit - standard (non-enterprise, pro)
    • Hard drives:1 X 128GB SSD - C:/ windows installed here ** NOT ENCRYPTED **
    • 1 X 2TB HDD - D:/ + E:/ **ENCRYPTED**
    • 1 X 3TB HDD - F:/ **ENCRYPTED**

    To turn off bitlocker:

    BitLocker Auto-unlock - Turn On or Off in Windows 8

    Also through an elevated powershell command you could try:


    Disable-BitLocker -MountPoint "C:"
    Hope that helps!

    Cheers,
