Windows 11 hardware requirements at a glance

Here’s the short list many buyers ask for. 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.

The 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 it is and core concept

Definition

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.

Why it matters

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 it works and step-by-step

Process

Here’s a simple flow:

Check CPU model and RAM in System Information.
Run tpm.msc to see TPM status.
Open System Information to confirm UEFI and Secure Boot state.
Update BIOS/UEFI if needed; turn on TPM and Secure Boot.
Add RAM or swap to an SSD if the PC is slow or short on space.
Back up files, then install Windows 11 and drivers.

Featured answer

To see if your PC can run Windows 11, 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 upgrade or a replacement laptop may be faster and cheaper.

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

Press Windows key + R, type tpm.msc, press Enter.
If it says “TPM ready to use” and version 2.0, you’re set.
If off or missing, check BIOS/UEFI for PTT (Intel) or fTPM (AMD).

CPU compatibility

Press Windows key, type System Information, open it.
Note the Processor line. Look up if it’s Intel 8th Gen+ or AMD Ryzen 2000+.
If it’s older (e.g., Intel 6th/7th Gen, AMD FX), Windows 11 is unlikely supported.

Secure Boot and UEFI

In System Information, check “BIOS Mode” shows UEFI.
Check “Secure Boot State” shows On. If Off, enable in BIOS/UEFI.
If the disk is MBR, it may need conversion to GPT before turning on Secure Boot.

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.

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.

When 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 and smooth data migration to Windows 11

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.

Professional installation, compliance and warranty in Brisbane

On‑site 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.

You get tidy cabling, ESD‑safe handling, thermal paste refresh where needed, and clear paperwork. This helps with vendor warranty, school BYOD rules, and insurance records after storm events.

Common problems in Brisbane

Weather and infrastructure

Summer heat and humidity 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 in West End or Woolloongabba may have patchy power points. Use a surge board or UPS.
NBN dropouts in outer suburbs like North Lakes or Springfield can interrupt Microsoft account setup.

Troubleshooting and quick checks

Short answer

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.

Quick checks

Try these safe steps:

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.

Safety notes and when to call a pro

Red flags

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.

Local insights and examples

Brisbane/SEQ examples

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.

FAQs

Q1: Do I really need TPM 2.0 and Secure Boot for Windows 11?

Yes. They are part of the security baseline. Many PCs already have firmware TPM (fTPM or PTT) and just need it turned on, plus Secure Boot. If your board has no TPM option, older desktops may take a TPM module, but very old gear may need replacement.

Q2: Can I upgrade a CPU to make my desktop compatible?

Sometimes. If your motherboard supports a newer CPU generation on the same socket, a BIOS update plus a supported Intel 8th/9th Gen or Ryzen 2000/3000 CPU could work. Laptops rarely allow CPU swaps. Weigh the cost against a newer system with warranty.

Q3: Is it better to upgrade parts or buy a new PC?

If your machine is from 2018 or newer, upgrades are often cheap and quick. Pre‑2016 systems, or laptops with soldered parts, are harder and may not pass CPU rules. When parts plus labour approach the price of a newer unit, replacing is usually the smarter play.

Sources and further reading

Windows 11’s baseline includes: supported CPU lists, TPM 2.0, UEFI firmware with Secure Boot, GPT disks, 4 GB RAM, 64 GB storage, DirectX 12 graphics, and a 720p display 9-inch or larger.
