Windows 10 Troubleshooting

Discover how Windows 10 works across workgroup, domain with Active Directory, and hybrid Azure cloud environments, and how authentication and resource access differ between on-premises and cloud domains.

Apply a structured troubleshooting framework that gathers user information, asks targeted questions, and defines a plan of action to remediate issues, while documenting results in a knowledge base.

Windows 10 built-in tools—Task Manager, Resource Monitor, and Performance Monitor—to monitor real-time resource usage and drill into processes. Schedule data collectors and view diagnostic reports for intermittent issues.

Explore Windows Reliability History, Event Viewer, and Steps Recorder to diagnose client machines. Learn to read timelines, filter logs, save reports, and capture step-by-step screenshots for troubleshooting and user education.

Explore the Windows 10 boot process from the power-on self-test to loading the boot configuration database, the boot loader, kernel, drivers, and the log-in screen.

Troubleshoot boot failures by inspecting the boot configuration database (BCD) and correcting missing or corrupted entries using recovery tools, command prompt, and bootrec /rebuildbcd in the Windows 10 recovery environment.

Resolve a hard drive boot issue by using the recovery environment and restore points in Windows 10, enabled via system protection settings, to roll back changes and verify boot configuration.

Identify how drivers enable communication with devices from keyboards to cameras in Windows, and use Device Manager and the driver store for viewing, updating, or staging drivers.

Troubleshoot mouse issues by checking batteries, USB connections, and airplane mode, then use a Windows 10 restore point in repair mode to roll back the driver.

Explore how Windows 10 authenticates users through local, domain, Microsoft, and Azure accounts, using password or MFA, and how DNS resolves domain controllers for logon.

Identify and fix a broken trust relationship between a Windows machine and its domain by using a local admin to remove from the domain and rejoin, reestablishing trust.

Identify local and roaming user profiles and how they load after authentication. Use folder redirection and mapped drives to reduce roaming profile size and login time, while preventing data corruption.

Investigate Alex's folder redirection, diagnose offline files with a sync error, update the backend shared folder permissions for the accounting group on DC1, and perform a sync to restore access.

Configure the Windows 10 client with IP address, subnet mask, and default gateway, using static or DHCP. Explore BYOD and domain considerations and troubleshoot network resource access.

Identify the tools to verify a client configuration in Windows 10 using the Settings app, network properties, IP config, PowerShell, and Network Diagnostics Wizard.

Diagnose dhcp client configuration issues on Windows 10 using built-in tools and ipconfig to renew leases. Restart the dhcp service on the domain controller to restore IP assignment.

Identify and fix client DNS issues by reviewing the network configuration, validating domain name resolution with nslookup, and switching from static to automatic IP settings to access resources by name.

Explore ntfs permissions on files, folders, and volumes, including granting and denying access for users, groups, or computers, with inheritance, basic vs advanced settings, and troubleshooting access issues.

discover how to verify NTFS and shared folder permissions, assess effective access rights, and resolve inheritance and deny scenarios to control network resource access.

Identify and verify NTFS permissions for shared resources using effective access, modify permissions to enforce proper access, and confirm who can read or modify files in a legal department scenario.

Configure and troubleshoot the encrypted file system (EFS) in Windows 10, including certificate authority, public and private keys, a bulk encryption key, and access control for files.

Explore how to implement efs encryption on documents, manage user certificates and access rights, and recover encrypted files with a recovery agent in a domain environment.

Troubleshoot Windows 10 browsers, comparing IE11 and Edge, and diagnose access to internal and external or cloud resources using DNS, gateway, and group policies.

Enforce security and configure the desktop environment using group policies, including login scripts, drive mappings, networking, printer permissions, and software deployment, via computer and user settings in Active Directory domains.

Compare group policy objects and group policy preferences, including enforcement, link order, inheritance, and item-level targeting, and use the group policy management console to apply, block, or enforce settings.

Learn how to diagnose GPO filtering issues using gpresult and gpupdate, compare Helen and Howard’s logons, identify denied HR desktop settings, and escalate to server teams for resolution.

Diagnose and fix a GPO link issue by verifying the GPMC link, enabling it, and forcing GPUpdate to apply folder redirection and display settings for the accounting OU.

Explore direct access as a transparent, bi-directional remote connection in Windows 10, comparing it to VPN. It explains the client experience, server-side components, and escalation paths.

Understand DirectAccess architecture and troubleshooting for Windows, covering server and client components, domain controllers, group policies, certificates, IP version 6, ISATAP tunneling, and connectivity checks.

Identify common causes of Windows 10 data loss, such as accidental deletion, malware, and hardware failure, and apply mitigations like mapped drives, folder redirection, and file history.

Learn how to set up Windows 10 File History to back up user profile folders automatically, restore deleted items, and include network locations with quotas.
