In Safetech, once you've finished decrypting, you have to go into Windows and run SBSETUP -UNINSTALL to remove the Safeboot files. Do you have to do the same thing in MDE 7.1.1 after running DE Tech? If so, what is the directory path and command?
Uninstalling MDE manually uses MSI strings found in the registry. More info can be found in KB76103.
