>To support Windows 10 devices in these mission critical customer environments we will provide Long Term Servicing branches at the appropriate time intervals. On these branches, customer devices will receive the level of enterprise support expected for the mission critical systems, keeping systems more secure with the latest security and critical updates, while minimizing change by not delivering new features for the duration of mainstream (five years) and extended support (five years). On Long Term Servicing branches, customers will have the flexibility to deliver security updates and fixes via Windows Server Update Services (WSUS) which allows full control over the internal distribution of updates using existing management solutions such as System Center Configuration Manager or to receive these updates automatically via Windows Update
