Hello Can someone point me to some direction because it works great on windows 7 however on windows 8.1, very often, especially after some updates, when I boot again I got some serious filesystem errors on every truecrypt mounted partition. Some time ago I figured the cause of this and found a key in regedit I could modify to ensure that windows wait for truecrypt to dismount all paritions on shutdown, however I forgot where it was . Can somebody point me there or tell me a better solution? I think that some update modified the key I mentioned above cause today I wasn't able to boot because of my windows partiton errors. Would be grateful for help.
