Ok, I think I found here what you mean with %~dp.
I think what you really want to do is this:
cd /D "%~dp0"
(!) But note that this will still not give you the right behaviour when you're trying to execute your batch while the current directory is on another drive as cd doesn't change the active drive.
Edit: Apparently (thanks @Yoopergeek) you can add the /D parameter to the cd command to let it also change the active drive.
The following is what we use, works great as a startup script:
on error resume next
dim WshShell
dim RegKey
dim ScriptVerKey
Set WshShell = CreateObject("WScript.Shell")
'checks to see if registry key exists, if it does, the cleanup runs.
RegKey = "HKLM\SOFTWARE\EDU\Cleanup\"
ScriptVerKey = WshShell.RegRead(RegKey & "JAVAOldVer")
if ScriptVerKey <> "1" Then
Cleanup()
Else
WScript.Quit
End If
Sub Cleanup()

The locking of the batch file/process from Task Scheduler is by design in Windows as you can produce some really unwanted results by trying to execute one command before the other is finished. You could however do the opposite/reverse of this and have multiple batch files that have these commands
set java_classpath java javaClassthat get called by one batch file. To do this, you would create a batch file that calls the other ones you created that have the code above. Please see this site for a good reference. I've done similar things with Command Prompt and automated XML-answer file Microsoft Office installs.
