    A very nice GUI for ERUNT!
    (but the website seems to be unaccessible right now)

    Btw a while ago I wrote a contribution to the forum on how to use ERUNT in Windows 7,without turning off UAC and without errors whats however…and even I mailed the developer of the program about it.

    Backup/restore your registry using ERUNT, even when running Windows7

    Have been using ERUNT & NTREGOPT version 1.1j for years (outstanding software)…if you are able to instigate a change out of those people, you will have truly accomplished something!
    Another piece of software to look into for use with the registy is “RegCompactPro.exe” from …does a good job in XP and Vista (haven’t yet tried Win7).
