First of all I didn’t write this. It’s so good (and FAST) that I wanted to make notes on it. The original file can be found here. I hope I explain the process a bit better. http://community.spiceworks.com/scripts/show_download/915.
First things first. There are 3 things that you will need to do.
You will need to download PsExec which is a sysinternals program. You will want to extract it to a folder that is part of the path. I copied my files to C:\windows
You will need to Download this file. I made a folder called “C:\scripts” and saved it there. I rename it to: “Uninstall Utility.hta”. If you are wondering what “HTA” is, HTA is an HTML Application are per: http://msdn.microsoft.com/en-us/library/ms536496(v=vs.85).aspx
You will also need to be an administrator of the remote machine you are scanning.
Now that you have everything setup just double click the the file. Enter whatever computer name you want to remove the software from and click “Show Items” button. Hitting “Enter” on the keyboard does not work.
Hope this helps!
