1)   RegdatXP 2.0
RegdatXP reads non active WinNT/2K/XP/2K3 registry files like ntuser.dat and usrClass.dat and compares them to the current Registry. The full version can recover data from corrupt registry files, and repair a corrupt file directly in many cases.

 2)   RegMedic 2.4.05
RegMedic can fix a corrupted Registry or install a new one, even when Windows cannot. This means no more formatting, no more reinstalling Windows. Fix all those little annoying non-function problems in Windows.
