📌 IMPORTANT
━━━━━━━━━━━━━

⚠️ Microsoft does not provide a permanent public ISO download for every Office generation.

For Office 2019 / 2021 / LTSC 2024, use the Office Deployment Tool + Office CDN rather than downloading unofficial ISO files. Microsoft’s own licensing documentation states that full ISO downloads aren’t provided for Office 2019, 2021 and 2024 through Volume Licensing. (Microsoft Learn⁠)

☑ Use official Microsoft sources whenever possible.

❌ Avoid modified Office ISOs, repacks, cracks, activators and unknown download mirrors.

⚠️ IT ENGINEER RULE
━━━━━━━━━━━━━━
❌ Don’t use registry “speed hacks” blindly.

❌ Don’t disable Defender to make a PC appear faster.

❌ Don’t disable random Windows services.

❌ Don’t delete system folders manually.

❌ Don’t run unknown PowerShell scripts from the internet.
☑ Measure first.
☑ Identify the bottleneck.
☑ Make one change at a time.
☑ Reboot/test.
☑ Document the change.

📌 Performance troubleshooting should be diagnosis first, optimization second.

🔐 ISO SECURITY RULE
━━━━━━━━━━━━━

⚠️ Never download operating-system ISOs from random Telegram channels, file-sharing sites or modified ISO repositories.

☑ Download from the vendor/project.

☑ Check SHA-256.

☑ Verify GPG/PGP signatures where available.

☑ Keep a versioned archive for systems that require older releases.

📌 SAVE THIS POST BEFORE YOU NEED IT.

A few particularly useful additions here are Proxmox, Rocky/Alma, TrueNAS, OPNsense and Clonezilla. Proxmox publishes both current and older ISO releases with checksums, which is useful when you’re supporting mixed environments. Rocky and Alma are especially useful for RHEL-compatible server labs, while Ubuntu and Debian cover a large portion of general Linux server work.
