How can I stop a PowerShell script from running?

Question

I have (so far unsuccessfully) tried to install SharePoint on my Windows 7/8.1 laptop.

It fails when installing a particular prerequisite (Windows Identification something-or-other).

But that's not my question, that's just a lead-up.

Every time I boot up my laptop since the failed install, a PowerShell script runs, re-trying the prereq install. I want to prevent that. I don't want the script to run any more. What must I do to send PowerShell a "cease and desist" directive regarding this particular operation?

Solution

Considering that this PowerShell script (usually with extension *.ps1) runs during the boot phase, I would have a look at the programs/services that have to be loaded at the startup and disable the execution of such script.

This could be done using msconfig (running it through WINDOWS + R) or using programs like CCleaner that allow to see and select/unselect the programs/service to load at the startup.

Do you know what script is trying to run?
