There are still many improvements to be made to Gutinteg. The current method of building the registry the first time the machine boots into Windows takes upwards of five minutes. This is time that users could be doing their work on the machine rather then waiting for the registry to finish building so they can log in. Solutions to this problem could be to use dosemu to build the registry. Another could be to use the Regutils[4], maintained by Michael Rendell, to build the Windows registry. Both solutions build the registry before booting into Windows, thus removing the wait that users see the first time a machine boots into Windows.
Another improvement is a companion program called dos-cache also developed at the TCC. This is a very simple script that makes an image of the Windows partition and stores it on the Linux partition of the same machine. The dos-cache program is then run nightly, or as needed, to rebuild the Windows partition. Since the image is kept locally on each machine, there is no network traffic and the procedure is much faster then running Gutinteg. Also, since the image is kept on the Linux partition, it is protected from malicious users because Linux supports true filesystem security.
A Final improvement is a program currently being developed at the TCC that would combine the features of RegView and Wholewheat. This would greatly simplify the package making process, as everything needed could be generated and compiled in one environment with little intervention required.
