    Under W7 I found that I had to run NTREGOPT registry optimiser and ERDNT registry recovery in SAFE MODE in order to avoid various warnings and errors. They then worked fine for me.

    if you are running your windows PC without this program you are NUTS! My butt was just saved because I had installed it on a friends PC which shortly afterward (days) suffered a catastrophic failure where it would not boot. Using the Windows CD I was able to finally get to the ERDNT folder and restore the registry to a known working condition. It was my final attempt after about 5 hours of trying to achieve some sort of progress on a PC that appeared to be suffering from some inexplicable Hard Drive failure. However the hard drive when placed in another PC was producing no symptoms of problems. God Bless the Writer of this software. It is OUTSTANDING!!!!

    Fabulous program. Saved me from the fbi virus and have used other times when registry corrupted. If your laptop will not load, easy solution if you have another computer is to place the hard drive in a usb case and connect to working computer. Modify inf file for the backup you want to use to change the drive letter to the drive letter your hard disk in the case is showing and then click on the backup. Have not tried yet on windows 7, but great for xp

    To get the daily Registry backups in Windows 7/Vista without completely turning off MS's UAC, run TweakUAC v1.0. Select 'Quiet Mode'. Now eruNT runs as it did on prior MS Windows versions.

    Be careful about directing your Registry backups to a drive other than C:. You won't be able to see them, nor run erdNT from outside of Windows, if you have to use the Recovery Console.

    To check which User accounts are included in the backup open the file ERDNT.INF - the restore paths for the numbered User folders are listed at the end of this file.

    To get ERUNT working correctly under Vista or Win7 see my install notes here:

    I installed and ran erunt for the first time. This looks like a great program; however, the question I have is: After doing the backup, I went to the users folder in the backup destination and noticed that the users are numbered. How does one know which user is which? I would like to be sure that a particular user is backed up. Any suggestions would be appreciated. Thanks, Joe.
