You uninstall the Windows client by using the appropriate Windows control panel, such as Add or Remove Programs.
If the Symantec Endpoint Protection client software uses a policy that blocks hardware devices, the policy blocks the devices after you uninstall the software. If you do not disable the device control by policy before you uninstall, use the Windows Device Manager to unblock the devices.
See your Windows documentation for more information.
