I have tried to restore my system to an earlier state to remedy the faulty uninstallation of a speech recognition programme, which tries to reinstall every time I start the computer. System restore restarts the computer but then tells me the restore process failed, once i am back to my desktop. OS is Windows 7 Home Premium and computer is an Acer Aspire laptop. System partition is encrypted using Truecrpyt. Could that be the problem? If I have to restore from a full image backup of the partition, will the encryption pose problems?
