How to uninstall a stand-alone instance of SQL Server 2005 manuallyNote SQL Server setup is a complicated process. SQL Server setup modifies lots of registry keys and DLL files. SQL Server setup also installs and updates permission entries and service registrations.
We test SQL Server setup procedures, both installation and uninstallation, in many configurations. However, we cannot test all configurations due to the number of third-party products and customer specific changes that can occur at the operating system level.
