In This Guide
This guide breaks down Windows 11 hardware requirements in plain Aussie English. It helps Brisbane homes and small businesses decide whether to upgrade parts or replace the machine. We'll cover the checks, common cheap upgrades, when replacement makes sense, and 2026 install costs in SEQ.
Confirm a supported CPU, 4 GB RAM, 64 GB storage, TPM 2.0, and UEFI with Secure Boot. Many systems only need TPM and Secure Boot switched on in BIOS/UEFI. If the CPU is too old, a desktop platform refresh or a replacement laptop may be faster and cheaper.
Windows 11 Hardware Requirements at a Glance
- CPU: Intel 8th Gen or newer, or AMD Ryzen 2000 series or newer.
- Memory: 4 GB minimum (8 GB+ recommended).
- Storage: 64 GB minimum (prefer an SSD).
- Firmware: UEFI with Secure Boot.
- TPM: version 2.0.
- Graphics: DirectX 12 capable.
- Display: 9-inch+, 720p.
- Internet: for updates and Microsoft account on Home edition.
Windows 11 Minimum Specs Explained in Simple Terms
Think of Windows 11 as a safety and speed upgrade. TPM 2.0 is a small chip or built-in firmware that keeps keys safe. Secure Boot checks boot files so sneaky malware can't start first. A modern CPU lets these features run well. UEFI is just the newer, friendlier version of BIOS.
On many 2018-2021 desktops, TPM is already there but turned off. Laptops may have fTPM in firmware. Old hard drives slow upgrades, so swapping to an SSD gives the biggest speed jump. If your system is older than 2016, parts may be limited and replacing the PC can be smarter.
What Windows 11 Hardware Requirements Are and Why They Matter
Windows 11 hardware requirements are the minimum parts and settings a PC needs to run Windows 11 safely. This includes a supported CPU, TPM 2.0, Secure Boot with UEFI, 4 GB of RAM, and at least 64 GB storage. These pieces work together to keep your device safe and smooth.
Up-to-date security helps with online banking, school logins, Medicare, and business tools. In Brisbane, we see lots of mixed setups: home studies, tradie laptops in utes, and small offices using MYOB or Xero. Meeting the requirements keeps those devices fast, patched, and ready for work or school.
How the Upgrade Works (Step-by-Step)
-
Check CPU and RAM
Open System Information and note Processor and Installed Memory. -
Run tpm.msc
Press Windows+R, type tpm.msc to see TPM status. -
Confirm UEFI and Secure Boot
System Information should show BIOS Mode UEFI and Secure Boot State On. -
Update BIOS/UEFI if needed
Turn on TPM and Secure Boot in BIOS settings. -
Add RAM or swap to SSD
If the PC is slow or short on space, do this before installing Windows 11. -
Back up files
External drive plus cloud copy before any major change. -
Install Windows 11 and drivers
Use Windows Update or the Installation Assistant.
How to Check TPM 2.0, CPU Support and Secure Boot
Use these quick checks on any Windows 10 or 11 machine.
TPM 2.0
Windows+R, type tpm.msc. "Ready to use" and version 2.0 means you're set. Otherwise enable PTT (Intel) or fTPM (AMD) in BIOS.
CPU Support
Open System Information. Note Processor line. Intel 8th Gen+ or AMD Ryzen 2000+ are supported.
Secure Boot
System Information shows BIOS Mode (UEFI) and Secure Boot State (On). MBR disks need conversion to GPT.
Storage
SSD with 64 GB+ free. Aim for 25-30 GB free for the upgrade. SATA or NVMe both work.
Tip: BIOS/UEFI keys vary. Common keys are Del, F2, F10, or F12 at power on. If you're unsure, check the screen on boot for the right key.
Pro tip: Many 2018-era HP, Dell and Lenovo desktops have TPM 2.0 but it ships disabled. A simple BIOS toggle moves you from "no" to "yes" without spending anything on parts. Check before you buy.
Common, Low-Cost Upgrades That Unlock Compatibility
- Turn on TPM and Secure Boot in BIOS/UEFI (free; sometimes a BIOS update is needed).
- SSD upgrade for slower PCs still on HDD. 500 GB SSDs are usually affordable and feel 3-5x faster.
- RAM bump to 8-16 GB for smoother multitasking. Many desktops and some laptops allow it.
- TPM 2.0 add-on module on select desktop motherboards (only where supported).
- CPU swap within the same socket on some desktops, paired with a BIOS update.
For Brisbane families and tradies, the biggest win per dollar is SSD + RAM, plus correct BIOS settings. It's quick, and it gives older gear a new lease on life.
Need a Brisbane Windows 11 Setup?
We test compatibility, fit RAM/SSD upgrades, enable TPM/Secure Boot, install Windows 11 and migrate your data. Same-day across SEQ.
Book a Windows 11 Setup - From $205/hrWhen Replacing the PC Makes More Sense Than Upgrading
- CPU is pre-2017 and motherboard lacks TPM 2.0 support.
- Laptop has soldered RAM or a dying battery, and parts are scarce.
- Motherboard is faulty or unstable after storms or power events.
- Upgrade parts plus labour costs are close to a newer device's price.
In these cases, a business-grade refurbished desktop or a mid-range new laptop can be better value. It saves time, cuts future hassles, and supports Windows 11 for years ahead.

Backups, Smooth Migration and Brisbane Install
Always back up before you start. Use an external drive for files, Desktop, Documents, and Pictures. Export email archives (like Outlook PST). Note app licences and sign-ins, including 2FA codes. Take photos of printer settings and Wi-Fi keys.
Upgrading the drive? We can clone your old drive to the new SSD, then tidy up Windows 11, drivers, and user profiles. For families and small offices, this keeps photos, MYOB files, and schoolwork intact with little downtime. If you're cloud-heavy (OneDrive, Google Drive), confirm sync status. Let it finish before you switch machines to avoid missing files.
Onsite and workshop options are available across the CBD, Northside, Southside, Bayside, Logan, Ipswich and Moreton Bay. We set BIOS/UEFI cleanly, apply firmware updates, and install Windows 11 with the right drivers. For business sites, we match device names, local policies, and BitLocker settings.
Brisbane weather and infrastructure issues
- Summer heat: can push old fans hard. Overheating causes throttling and setup crashes.
- Storms: trigger power flicks. Sudden shutdowns may reset BIOS, turning off TPM or Secure Boot.
- Older buildings: West End or Woolloongabba may have patchy power. Use a surge board or UPS.
- NBN dropouts: in outer suburbs like North Lakes or Springfield can interrupt Microsoft account setup.
We often see Dell OptiPlex desktops in offices around the CBD and Fortitude Valley that pass Windows 11 after TPM and Secure Boot are switched on. At home in suburbs like Carindale, Chermside and Sunnybank, a simple SSD upgrade makes a big speed difference, then Windows 11 runs fine. Tradies around Logan and Ipswich bring in toughbooks with worn hard drives. An SSD and a fresh Windows 11 install keeps job apps and maps quick on site. For students near St Lucia and Kelvin Grove, we tidy OneDrive sync and school portals so class starts without hiccups.
Troubleshooting and Quick Checks
If Windows 11 won't install, check TPM and Secure Boot first. Update BIOS/UEFI then try again. If the CPU is too old, consider an SSD and RAM refresh with Windows 10, or move to a newer PC for a clean Windows 11 setup with full security features.
- Run tpm.msc to confirm TPM 2.0 status.
- Open System Information to check UEFI and Secure Boot state.
- Confirm disk space: keep at least 25-30 GB free for the upgrade.
- Update BIOS/UEFI using the maker's tool; keep the laptop on power.
- Clean dust filters to lower temps before a long install.
- Plug into the modem during setup if Wi-Fi is flaky.
Watch out: Stop and get help if you see BitLocker lock screens, BIOS passwords you don't know, or strange drive partitions. Avoid CMOS resets unless you've recorded current settings. If a firmware update fails mid-way, don't power-cycle. For business PCs with compliance needs, get a tech to keep audit trails clean.
