Windows & Intune
Hands-on notes for Windows 10 deployment, upgrade troubleshooting, and Intune policy management from the field.
What this category covers
Posts here focus on the operating system layer: getting Windows 10 onto devices, keeping upgrades predictable, and shaping behaviour through Intune. Two recurring threads are upgrade and time-synchronization issues on Windows 10, and the practical use of Intune Policy CSPs for things such as Internet Explorer site-to-zone assignment.
Deployment & upgrades
Coverage of Windows 10 deployment scenarios and post-upgrade behaviour. Older posts documented issues seen after upgrading to specific Windows 10 versions, including a documented case of time reversion on version 1511.
Upgrade task sequences
Patterns for sequencing Windows 10 upgrades alongside existing ConfigMgr and Autopilot workflows.
See Autopilot content →Managing Windows 10 deployments in enterprise environments often requires a careful balance between automation and hands-on troubleshooting. Upgrade issues can surface unexpectedly, from time-synchronization failures that break domain trust to driver conflicts that halt a task sequence mid-installation. Building a reliable lab environment to test these scenarios before pushing to production is a common practice among IT administrators. Whether you are working with Configuration Manager task sequences or standalone media, understanding the common failure points helps reduce downtime and user frustration. Logs, validation scripts, and phased rollouts each play a role in keeping deployments predictable across diverse hardware inventories.
Intune policy management extends beyond simple configuration profiles into more granular control of device behaviour. Policy configuration service providers allow administrators to enforce settings such as Internet Explorer site-to-zone assignments, certificate deployment, and compliance rules. These policies apply across managed Windows 10 devices whether they are corporate-owned or bring-your-own. The challenge often lies in understanding which policies conflict, how targeting works with dynamic groups, and what to do when a policy fails to apply. Testing policies in a pilot ring before broad deployment remains a best practice for avoiding unintended configuration drift.
The intersection of on-premises Configuration Manager and cloud-based Intune creates a hybrid management scenario that many organisations navigate daily. Co-management allows workloads to be shifted gradually, letting teams retain existing processes while adopting modern management capabilities. Windows Autopilot further simplifies the device lifecycle by reducing the need for imaging and allowing users to self-provision. PowerShell scripts and Graph API calls can automate much of the enrolment and configuration workflow, making the transition smoother. Understanding how these tools complement each other is key to building a sustainable device management strategy.
Troubleshooting Windows 10 upgrade failures often involves digging into setup logs, analysing compatibility data, and addressing blocking issues such as incompatible drivers or applications. A methodical approach helps isolate whether the problem lies in the operating system image, the task sequence logic, or the target hardware. Many administrators maintain a knowledge base of recurring issues and their resolutions, building a reference that accelerates future troubleshooting. Keeping upgrade rings small and monitoring telemetry from pilot devices provides early warning of problems. Consistent documentation of findings helps teams avoid repeating the same investigation steps across different upgrade cycles.
Intune policy & CSP
Worked examples of pushing settings to Windows 10 through Intune, including using the Policy configuration service provider to control Internet Explorer security zones.
