270 step-by-step IT guides and fixes across Windows Server, Microsoft 365, Teams, Windows, Docker, and virtualization.
Pillar Guide
Windows 10 support ended October 14, 2025. Here's what that means, your options — upgrade to 11, ESU, replace, or stay — and a clear checklist to decide.
Teams microphone not working? Fix it with Windows mic privacy settings, the right device selection, a test call, headset and Bluetooth quirks, drivers, and a cache clear.
Use message trace in the Exchange admin center to find where an email went: read Delivered, Pending, Failed, and Quarantined statuses, and run a detailed trace for older mail.
Force AD replication on demand with repadmin /syncall /AdeP, replicate now in Sites and Services, and verify the result with repadmin /replsummary and /showrepl.
Back up and restore Proxmox VMs with vzdump: snapshot vs suspend vs stop modes, scheduled jobs, storage targets, restoring to a new VMID, and retention rules.
Hyper-V checkpoint failed? Fix it by checking disk space, VHDX permissions, VSS writers, and production vs standard checkpoints — with the AVHDX chain explained.
Install Docker Desktop on Windows 10 or 11 with the WSL2 backend: enable virtualization, run the installer, verify, and fix the common setup errors.
Forgot your Windows 11 password? Reset a Microsoft account online, use local account security questions, fix a PIN, or use a password reset disk — the safe way.
Create a team in Microsoft Teams from scratch, a template, or a group. Understand teams vs channels vs chats, owners vs members, and channel types before you start.
