(aka "reliable recovery for EFS'd files")
One of the most critical outstanding issues with the use of EFS in the enterprise is that the EFS component 'driver' does not automatically start using "better" EFS certificates when they are enrolled. This command-line application wlil help an organization migrate EFS-encrypted content to be encrypted with centrally-enrolled (and ideally key-archival backed) digital certificates suitable for EFS.

Future Enhancements to EFSCONFIGUPDATE
There are a number of opportunities to extend the functionality for this tool, many of which I've heard from one or another customer as something they'd like to see. Time (and demand) permitting, I'll see about adding a few of these in future versions of this tool. (Your input - through the Issue Tracker
- can significantly influence what I invest my time in.)
- log significant errors in the Application Event Log
- Archive any non-matching EFS certificates
- provide multiple ways to identify the specific CA from which desired certificates should have been enrolled
- don't just select the first matching certificate but the "best" matching certificate
- optional capability to enroll for a matching certificate if no matching certificate is found
- possible integration of this tool with the EFS Assistant (which you can find here: http://www.codeplex.com/EFSAssistant/)
- localization by extracting all non-localized strings into appropriate resource files
- additional error & exception handling
Other Free Tools to Help with an EFS Deployment
- EFS Assistant: eases the burden of enforcing encryption on sensitive data files, no matter where they're stored on disk
- EFSDump: provides access to some metadata about EFS-encrypted files, and may be the only remaining useable tool for Windows Vista since EFSInfo is not supported on Vista
