Numbers of Connecting Devises,
Numbers of Remote Site,
Remote Site Bandwidth,
Numbers of Application and Image and capacity of them,
Integrate Intune – If you want to manage devices which are non-join domain and non-Windows Operating System,

                Correctly Assign Job Role what your expecting with SLAs
                                    Patch Admin – Manage and Distribute all the patches
                                    Image Admin – Test and Deploy correct image to required devises
                                    App Admin – Test and deploy correct Apps to correct user or devise groups

KEY BENEFITS
                Patch Management and Reporting
                Application Management and Reporting
                Assets Reporting and Inventory – Asset Intelligent
                Operating System Deployment (OSD)
                Settings Management (DCM)
                End Point Protection

In this Article we are considering only How to do the More than 95% Windows Client Patch Compliance
Guidelines for How to do the More than 95% Windows Client Patch Compliance
Purpose –                      
Ensure timely delivery of Security updates, help make environment secure and provide consistent user experience.
Target Compliance –   
Deploy active exploit update to 95% of computers with three business days.

Compliance period –        Comply within 3 or 7 business days, as appropriate.  

Recommended Patching Process –
Pre-Update Deployment –  
Silent, Interactive or on-demand patching you can choose for this.
                Create Patch testing Groups with covering all the Operating Systems & application,
                Provide better awareness session about patch testing collection devices users,
                Prior notice them, before start deployment,
                Deploy, Monitor, Create Risk Mitigation plan, Request Feedback.

                Defined correct boundaries and boundary group with including correct site servers
                Deploy Automatic Patch Deployment rules for each device collections
                Use WSUS to install the configuration manager client
                Verify SCCM Client settings

                Weekly or at least Monthly Client PC restart schedule
