Use the Add or Remove Programs option in the Control Panel. In Windows 7 and Windows Server 2008, that option is available under Programs and Features.

You can also uninstall Splunk Enterprise from the command line by using the msiexec executable against the Splunk installer package:

C:\> msiexec /x splunk-<version>-x64.msi

Note: Under some circumstances, the Microsoft installer might present a reboot prompt during the uninstall process. You can safely ignore this request without rebooting.

Note: These instructions will not remove any init scripts that have been created.
