🚨 IT Infrastructure Daily Briefing | 4 October 2026

What IT professionals should know today:

🖥️ Windows 11 26H2 — Rolling out; start enterprise pilot testing and application compatibility checks.

🔧 Windows Server 2022 — Mainstream support ends 13 Oct 2026. Start planning your Server 2025 migration strategy.

🔐 Microsoft Security — AI-powered attacks and the growing CVE volume make AD, Entra ID, PowerShell, RDP and privileged-account hardening critical.

☁️ Azure India — Microsoft’s expanded India cloud footprint strengthens opportunities for hybrid cloud, data residency and disaster recovery.

🚀 Skills for 2026 — Focus on Azure, Entra ID, PowerShell, Terraform, Azure Monitor, Defender, Git/CI-CD and Infrastructure as Code.

🔐 PowerShell Script #52 — Audit Stale Service Accounts with Privileged Access

🚨 Are inactive service accounts still holding privileged access in Active Directory?

This read-only PowerShell audit identifies enabled accounts with service-account indicators and checks 90+ days of inactivity, SPNs, PasswordNeverExpires, adminCount, and privileged-group membership.

✅ Detect stale service accounts
✅ Identify privileged access
✅ Check SPNs & non-expiring passwords
✅ Assign CRITICAL / HIGH / REVIEW priority
✅ Export a detailed CSV report

🛡️ Security workflow:
Discover → Identify → Validate Owner → Check Dependencies → Reduce Unnecessary Access → Document → Re-audit

⚠️ Important: Inactivity does not prove an account is unused. Verify applications, scheduled tasks, backups, integrations, and DR dependencies before disabling or changing an account.

👉 Follow for PowerShell Active Directory Security Audit #53.

🧠💻 Laptop RAM Problems? | Day 6

Is your laptop freezing, crashing, showing BSODs, or randomly restarting? Faulty or poorly seated RAM could be the culprit.

🔧 Check these first:
✅ Check RAM usage in Task Manager
✅ Run "mdsched.exe"
✅ Reseat the RAM
✅ Test each RAM stick individually
✅ Check RAM compatibility and BIOS detection

💡 Pro Tip: If you have two RAM modules, test them one at a time to identify a bad module or slot.

Diagnose first. Replace second. 🔧

Today’s focus: designing, managing, and optimizing Hyper-V storage for reliable VM performance.

🔹 VHD vs VHDX
🔹 Fixed, Dynamic & Differencing disks
🔹 SSD/NVMe, SAN, SMB & Storage Spaces
🔹 VM storage configuration with PowerShell
🔹 Checkpoints & Live Migration
🔹 CPU, RAM, storage IOPS & network performance
🔹 Storage troubleshooting and VHDX issues
🔹 VM backup & recovery best practices
🔹 Production storage design and performance monitoring

💤 WHICH SLEEP MODES DOES YOUR WINDOWS PC SUPPORT?

Open Command Prompt as Administrator and run:

powercfg /a

🔍 It shows supported power states like Sleep (S3), Hibernate, Hybrid Sleep, Fast Startup, and Modern Standby (S0)—and can explain why a mode isn’t available.

💡 IT Pro Tip: Don’t assume every Windows 11 PC uses traditional S3 Sleep. Modern systems may use S0 Low Power Idle.
