I see a lot of newgroup posting starting with "How do I perform registry operation XYZ on a lot of remote PCs?" Aelita has written MultiReg to do just that.

MultiReg provides centralized Registry management, analysis, and editing capabilities. With MultiReg, administrators can quickly and easily change system settings on multiple computers, implement and maintain company systems policies, standards, and security enhancements.

MultiReg is not intended to replace Windows NT Registry Editor (regedit32.exe) but to add functionality necessary for managing multiple computers.

MultiReg allows you to work with one or a group of computers. Computers can be grouped by location, department, functionality, etc.
