Thank you so much Peter!
I did the following so that the program always starts up when I start up Windows 7:
Click on Start and then type: gpedit.msc
Click Enter
Doing so will open the "Group Policy Editor"
Now, on the left-side column, find where it says: "User Configuration"
Then, make sure the folder is expanded on the left side so you can see: "Windows Settings." If Windows Settings isn't expanded to show options below it, click on the plus arrow on the left side of Windows Settings.
You will see "Scripts (Logon/Logoff)" (still on the left-side column)
Click once on "Scripts (Logon/Logoff)."
Then you will see two items in the main window: "Logon" and "Logoff."
Double-click on Logon.
Then in the window that appears, click on "Add."
Now, you will see a window appear that has two places to enter information.
You will want to enter the pathname of the file you wish to have open at Windows startup where it says: "Script Name."
This pathname is wherever you've decided to save the PDSpeed.exe file.
I personally decided to save it in the "C:\" directory in a folder called "PDSpeed."
So, what I entered was (without quotes): "C:\PDSpeed\PDSpeed.exe"
You can just leave the "Script Parameters" section blank.
Click "OK" to finish adding the command and then click "OK" one more time to close the "Logon Properties" window.
Now, you will not need to manually start up the script, it will start automatically everytime Windows starts up.
Please note that these instructions were made for Windows 7, so they may vary for different versions of Windows.
I hope this helps other people.
Thanks again Peter for your useful script!
