So in case you’re like me and assumed you’d do this through the SQL Server Management Studio interface, you’re unfortunately wrong. This is actually accomplished through the far less logical process of “Uninstalling a Program”. I’ll help you through the steps here.
Go to your Control Panel, and under Programs and Features, find your SQL Server Installation.
A verification step will start up with the wizard.
Next, select your SQL instance.
Only choose the services associated with that particular instance.
Yet another verification Step.
Oh, and in case you weren’t yet convinced, here’s another verification step.
And all went well.
Voila, you’re all done!
