    Hi

    Just downloaded SysinternalSuite , unzipped it and get a folder
    with loads of .exe files and a few other bits and pieces. Just
    wondered if the components applications are run separately
    or can they all be bundled to run as one Application i.e

    SysinternalSuite.exe

    1. Techexpert says

      You just need to run the autorun.exe from the extracted folder. All the other files are also associated with Sysinternals Suite, so ignore them.
      Download:  SysinternalsSuite.zip
      How to run: Unzip the SysinternalsSuite.zip file and then double-click on autorun.exe file from the extracted folder to start the  Sysinternals Suite. See the screenshot below.
