Windows 11 Upgrade Checklist
for Brisbane PCs & Small Business

This guide helps Brisbane homes and small businesses check Windows 11 compatibility, plan upgrades, and avoid downtime. Most PCs only need a BIOS setting change or simple parts like RAM or an SSD upgrade. We'll cover the checks, costs, and how to roll out across staff with minimal disruption.

What a Windows 11 Upgrade Means and Why It Matters

A Windows 11 upgrade means moving a PC from Windows 10 to Windows 11 and meeting the hardware rules. Key checks include TPM 2.0, Secure Boot, CPU compatibility, RAM requirements, and storage space.

Windows 11 adds stronger security, better battery life on laptops, and smoother Teams and Office use. For Brisbane shops, tradies, and offices, staying current lowers risk during storm season and keeps MYOB, Xero, and cloud tools running well. Old boxes can still be useful with smart upgrades.

How the Windows 11 Upgrade Works (Step-by-Step)

1. Run Microsoft's PC Health Check
   Quick pass or fail with a list of failed requirements.
2. Confirm TPM 2.0 and Secure Boot
   Press Windows+R, type tpm.msc for TPM status. Open System Information to see BIOS Mode (UEFI) and Secure Boot State.
3. Check CPU compatibility
   Aim for Intel 8th-gen or newer, AMD Ryzen 2000 or newer.
4. Check RAM requirements
   8 GB sweet spot for light work. 16 GB if you multitask or use design apps.
5. Check storage
   Free 64 GB minimum but plan for 20-30 GB extra. Consider an SSD upgrade if you're still on a hard drive.
6. Update BIOS/UEFI
   Vendor tools often add TPM or stability fixes.
7. Back up
   System image, user data, and a restore point. Test the backup opens.
8. Upgrade parts if needed
   Add RAM, fit an SSD (SATA or NVMe), enable TPM and Secure Boot in BIOS.
9. Install Windows 11
   Use Windows Update or the Installation Assistant. Let it complete drivers and updates.
10. Post-checks
    Sign in, test apps and printers, verify BitLocker and antivirus, re-run Windows Update.

Quick Compatibility Checks: TPM, Secure Boot, CPU

Most 8th-gen Intel and 2nd-gen AMD Ryzen or newer are okay; older chips may fail. Many PCs only need a BIOS setting change to enable TPM and Secure Boot.

RAM and SSD Upgrades Give the Biggest Speed Boost

Even if your PC passes the Windows 11 checks, the experience can feel sluggish on old parts. Two cheap upgrades make a huge difference:

• RAM: 8 GB minimum, 16 GB sweet spot. Matched DDR4/DDR5 kit, dual-channel.
• SSD: If still on an HDD, swap to a 500 GB-1 TB SATA or NVMe SSD. Boots drop from 2 minutes to 20 seconds.

Costs in Australia for a Windows 11 Upgrade

Honest 2026 pricing for Brisbane upgrades and rollouts:

Plan 1-3 hours per PC for backup, upgrade and install; more for old or complex setups. After-hours rollouts may carry a small surcharge but reduce staff downtime.

Common Problems in Brisbane: Heat, Storms, NBN

Heat and humidity

Summer temps in garages and roof-spaces can throttle older PCs. Plan upgrades in air-con and add case fans when fitting new parts.

Storms and power flickers

Short outages during updates can corrupt installs. Use a UPS during firmware updates and Windows installs.

Older buildings

Limited power points and daisy-chained boards cause brownouts. Avoid updating many PCs at once on one circuit.

NBN quirks

HFC in Carindale and Coorparoo can slow at peak. FTTN in older parts of Ipswich or Logan can be unstable. Schedule large downloads off-peak or cache the installer onsite.

Across Brisbane we see common patterns. CBD and Fortitude Valley offices: Dell OptiPlex and HP EliteDesk from 2016-2017 often fail CPU rules but can run well on Windows 10 with fresh SSDs until replacement. North Lakes and Springfield families: laptops with 8 GB RAM and a small SATA SSD run Windows 11 nicely after a BIOS update and enabling TPM. Sunnybank and Eight Mile Plains home offices: custom PCs with 7th-gen Intel pass everything except CPU - a budget platform refresh fixes it while keeping the case and PSU. Logan and Redlands tradies: rugged laptops often meet CPU rules but need an NVMe upgrade for better CAD and plan reading on site. We fit UPS units in Indooroopilly and The Gap to protect upgrades during storm cells.

Troubleshooting and Quick Checks

If PC Health Check says no, check BIOS for TPM (PTT on Intel, fTPM on AMD) and Secure Boot, then update BIOS. Add RAM or an SSD if performance is weak. If the CPU is too old, plan a platform refresh or keep Windows 10 with strong backups until replacement.

• Press Windows+R, type tpm.msc. Status should show "TPM is ready for use".
• Open System Information. BIOS Mode should be UEFI; Secure Boot State should be On.
• Reboot to BIOS/UEFI. Look for PTT/fTPM and Secure Boot settings; enable them.
• Update BIOS using the vendor tool. Plug into mains or a UPS during the update.
• Check CPU generation in Task Manager or System Information.
• Run a SMART check with your drive tool. If "Caution" appears, replace the drive before upgrading.
• Free up space by removing temp files and old installers.
• Back up to an external drive and to a cloud account before any major step.

Fleet Rollouts: Backup, Test, Stagger

For business sites, downtime is money. Our checklist for Brisbane fleet rollouts:

• Run PC Health Check on every device in advance.
• Pilot the upgrade on one PC. Test apps, printers, BitLocker.
• Schedule out-of-hours work in groups of 3-5 PCs to keep IT on standby.
• Image each PC before changes. Keep a 30-day rollback image offsite.
• Document which PCs failed CPU rules and plan a refresh budget over 6-12 months.
