Bitlocker drive informs me I need a newer version of windows


Honorable Member
Hi Guys,

I went to bed last night with a reasonably happy computer, came down this morning and one of my drives wouldn't unlock, giving me a message saying that "The BitLocker encryption on this drive isn't compatible with you version of windows. Try opening the drive using a newer version of Windows." urm, 8.1 as far as I am aware is the newest.

Has anyone got any idea as to why and a possible solution?

Kind regards

I know it sounds silly, but try removing the drive from your computer, blow off any dust, and re-attach it to a different SATA port. Make sure your BIOS settings are correct for that port to be enabled, etc.
Also if your feeling frisky, look for an update to your BIOS and read any change log it may have, see if there have been any changes to its TPM module, if so update.
