I have modified a script that I created for someone else that should do what you need. You will need to rename the script to LoginDate.vbs

What the script does is when it runs it checks registry for a specific key and value.
If the Key doesn't exist, the Script calls a function, and then writes todays date to the Registry.
If the Key does exist, but the Value is not todays date, the Script calls a function, and then writes todays date to the registry.
If the Key does exist, but the Value is todays date, the Script Quits.

All you should need to do to get it working is add your script to the ScriptToRun Function - I have included comments in the script, and a couple of WScript.Echo lines so that you can see what it's doing whilst it's running.

Hope it helps.
