In Safe Mode, Windows has reduced functionality, because only the core components have been loaded.In order to uninstall a program in Windows, the Windows Installer Service has to be running. If you try to uninstall software in Safe Mode, Windows will just inform you that: “The Windows Installer Service could not be started.” Trying to start the service manually will only get you: “Error 1084: This service cannot be started in Safe Mode.”

All of the services that are allowed to start in Safe Mode are stored in the registry folder


you have to add a REG_SZ key with the service name (not the display) and the value data Service . The service name of the Windows Installer Service is MSIService

Note:-It is not always possible to uninstall software in Safe Mode because the corresponding installer program requires certain services to be running.
