    Thanks for great tool!

    Do you plan add multilingual support for GUI?

      Hello Wojciech,

      Localization is in the works, and will be a functionality of the next version.
      We are looking for people to submit the translations.
      I’ve send you an e-mail, regarding this.

    /r switch doesn’t seem to work with this version.

      Hi John,

      I’ve just checked the /r switch in this version, and everything about it works for me.
      It changes both the text on the form, and correctly restarts the computer when the countdown hits zero.

      Please elaborate on your problem with the /r switch.
      What exactly isn’t working for you?
      Which OS are you running the utility on?

      If you are using /r with /f and /c in the command line, try removing the /f. Since the /c implies /f already, it does not need to be there. I was seeing the same issue. My command line was ShutdownTool_NoBack.exe /r /t:300 /m:0 /d:”Message to user” /f /c

      When i removed the /f it worked.
      ShutdownTool_NoBack.exe /r /t:300 /m:0 /d:”Message to user” /c

    would it be possible to add a parameter to skip the countdown when no user is logged on? Or do i miss the trick how it can be combined with standard techniques?

        Hi Claus,

        are there any news regarding the release date of the new version?

    Thank you for all your work creating this tool.

    How can I use the Registry Key command line switch to run shutdowntool.exe based on only if a reg key exists? (If I didn’t know any of the Name/Value pairs under the reg key ahead of time) Or is there some way to check for the “Default” valueless Name/Value pair using the /er: switch?

    The reg key I would like to check for is: HKLMSOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateAuto UpdateRebootRequired

    Hi Claus,
    Thanks for the wonderful and easy to use tool. I have updated the same on my blog.
    It seems that the example command is wrong, and that runs fine when i remove the backslash() before the Quotation marks as given below:
    Command: /t:300 /m:60 /d:”Because I said so!” /f /c

      Hi Rajeesh,

      You are absolutely correct, thoose escaping backslahes aren’t supposed to be there…Damn copy-paste!
      Thanks for the notification, i’ve corrected the “typo”.

    Hey Kent,

    I was in your CM 2007 R3 Cleanup class at MMS and you showed the shutdown tool. Seems really slick! It got me thinking, do you have a tool with simialr fuctionality that would close IE rather than shutdown/reboot? I often have to close IE with 3rd party updates, jre, quicktime, etc… I hate having to force close IE sessions if a user could be potentially working.

    The tool is amazing! Many Thanks.
    I need your help. I am in the IT training and would like to introduce the tool in the school. Unfortunately, I do not understand how I need to integrate the tool into SCCM so that runs after a software Installation from SCCM. I read the article How to configure the tool In Configuration Manager but dont undestand where I Need to create the programs in the package to control the Shutdowntool..
    I would like to install a software via SCCM which runs the tool after the instalaltion with the Notification Window.
    Did exist an German language pack for the tool ?
    Thanks in advance
