I'm running Windows 8.1 and initially had bitlocker among my apps, but I reinstalled to factory settings and it disappeared! It's still in the O.S., I can find it in Windows, but it does nothing. I can't enable it because I don't have secpol.msc. Is there some other way to enable bitlocker so I can use it? Thanks for any help. I can't find anything on the net of use.
