    Editing the registry

    When editing the Windows Registry, some suggest using "regedit.exe" while others sometimes suggest using "regedt32.exe". What is the difference between the two? I haven't been able to discern any. If I launch one, I can't launch the other to do a side-by-side comparison. I run Windows XP pro, but I think this is a "general" windows question.

    Cheers,
    Regards,

    PaulB,
    For one thing, regedit32 is a little faster than regedit. Also it will "remember" where you were last and come back to it the next time you open it. <img src=/S/nosleep.gif border=0 alt=nosleep width=27 height=15>

    I keep shortcuts to both in my editors folder, but end up using "32" more often.

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Re: Editing the registry

    Hi, Paul ~

    Yes, your query is one of a general windows nature.

    'Regedit' is the registration editor for 16-bit Windows, which is used to modify the Windows registration database. 'Regedt32' is the configuration editor for Windows NT, which is used to modify the Windows NT configuration database, also known as the 'Windows NT Registry'. 'Regedit' is included in Windows NT for compatibility with previous 16-bit applications and provides a method for examining 'REG.DAT' under Windows NT. 'Regedt32' Although not explicitly noted, it seems the impression that 'Regedt32' is more powerful.

    According to MS, 'Regedt32' in NT & Win2K OSs does not allow you to search for the actual registry values or data, only registry keys. Also according to MS, 'Regedit' is the program that will remember where you were last and come back to it the next time you open it and that 'Regedt32' does not exhibit that behavior, but in my experience with XP all of the above does in fact occur with both 'Regedit' and 'Regedt32'.

    For more info on the differences between 'Regedit' and 'Regedt32' and uses of each, please peruse the articles here.

    Hi, Hans ~

    Nice call! <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    I have all those articles saved locally and the version of MSKB 141377 I have archived (published Dec 17, 1995 - saved June 4, 2002) is vastly different than the version that is currently published (published June 7, 2003 - saved June 26, 2003).

    Is there a facilitation of notification for updated MSKB articles available??

    Re: Editing the registry

    Since you have Windows XP, there is no difference - according to Differences Between Regedit.exe and Regedt32.exe, one of the links in the reference provided by Bruce Krymow:
    <hr>In Windows XP and Windows Server 2003, Regedt32.exe is a small program that just runs Regedit.exe<hr>
    Regedit and Regedt32 were different in Windows NT 3.x, Windows NT4.0 and Windows 2000.

    Re: Editing the registry

    Paul, you've already gotten your answer - but it's worth noting two things.

    REGEDT32 is a stub file that launches REGEDIT, which is why there's no difference. It's the same application.

    REGEDT32 used to be preferred on the NT platform because it supported the security model for NT, as well as some extended datatypes that REGEDIT did not. If you ever have to work on an NT 4 system, that's something to keep in mind.
