JSI Tip 2880. How do I restore selected registry keys/value to their initial/previous settings, in Windows NT 4.0?

In tip 2809, I described the procedure for Windows 2000.

Windows NT 4.0 stores the registry hives in the %SystemRoot%Repair folder, and on an ERD, in compressed format.

To perform the subject function for Windows NT 4.0, you must first expand the compressed hive from the %SystemRoot%Repair folder, or from an ERD, to a temporary folder. Then load the hive, as in step 03, from the temporary folder. To expand the compressed hive:

Expand

Examples:

To expand the System hive, from the %SystemRoot%Repair folder, to C:TEMPSystem:

Expand %SystemRoot%RepairSystem._ c:tempSystem

To expand the Software Hive from an ERD, to C:TEMPSoftware:

Expand A:Software._ C:TempSoftware
