Despite this, users with a very small amount of Windows server installations have been looking for ways to install Windows Defender in order to provide at least a basic level of security. It is important to note that Microsoft Security Essentials is designed to provide a basic level of free protection for home or small business PCs rather than important server infrastructure. Microsoft Security Essentials provides most of the protection methods that Windows Defender does with the exception of rootkit and bootkit protections.
