    Hey,

    I am attempting (as an administrator with FBWF disabled) to add a registry String to an existing registry key within HKLM.

    When I reboot the Thin Client (X90L, XPe, SP2) the registry string I entered into the registry is deleted. I do not have WDM setup.

    What am I missing here?

    Help!

    Thanks

    In which key are you trying to add your string?

    No sure but I guess this is created each time automatically while the OS boots up.

    Possibly,

    On my Windows XP machines I am able to add this string to that location and upon reboot it remains.

    I just attempted to add a string called Test with a value of Test under the Key HKLM and rebooted the X90L and it was deleted as well, I attempted to change the permissions on the Key HKLM and they reverted back to what they were before I made the changes on reboot.

    I added a string called Test to the key HKCU with a value of test and that remained during a reboot.

    So it appears the entire HKLM is rewritten each time the unit is rebooted. Any ideas how to get this string to stay after a reboot?

    Thanks

    Check out for a file called regperistent.exe and modify the .ini file accordingly.
    Maybe that helps.

    Ok, I didn’t get regpersistant.exe to work. I’m still not entirely sure what it is supposed to do, I think something along the lines of saving wireless connection details even when the write filter is enabled.

    Anyways, this is what I did to solve my issue.

    I created my registry entry,
    Export it to C:
    create a batch file with the following line save it in C: as well
    regedit.exe /s “name of reg file”

    I then opened gpedit.msc, Computer Configuration, Windows Settings, Scripts (Startup) and then added my batch file to the startup.

    Seems like a lot of work to add a simple registry entry, not sure how common this would be to anyone else but felt I should post my workaround.

    Cheers
    Jeff
