I have done some research on using BitLocker in an environment where the machines do not have a TPM and it appears you will need to utilize a Flash Drive for it to work properly. This seems to be the case for Windows 7 and Windows 2008 R2.
I have read conflicting information pertaining to Windows 8 and Windows 2012 R2 for which claim BitLocker can be utilized without the use of TPM and a USB drive.
Is this true? Has anyone had experience using BitLocker without TPM or a USB flash drive? If so does it only pertain to Windows 8 and 2012R2 as some information suggests? If this is the case is there a reputable website I have yet to find that explains this in detail?
