You are setting up a new PC, rebuilding an old one, or replacing a drive, and Windows asks for a licence. A quick search shows Home, Pro, OEM, retail, USB, DVD, key-only and a dozen price points, and it is not obvious which one is right for you. Pick wrong and you either pay for features you never use or discover, months later, that you are missing the one tool your work needs.
This guide explains what a Windows licence actually is, what the differences between Windows 11 Home and Pro mean in daily use, what OEM and retail licences mean, and how to check your hardware before buying. We then walk through our pick, Microsoft Windows 11 Professional OEM 64-bit, including who should skip it, and compare it with four other options in our range.
Everything here is general guidance plus the details published on each product page. If you are unsure about a specific build, send us the details through our contact page before you order.
What is a Windows licence and why it matters
Windows is the operating system: the software that sits between your hardware and every app you run. A licence is your legal right to run it. Without a valid licence, Windows still installs on most PCs, but it nags you to activate, locks some personalisation settings, and is not something a business should rely on. A genuine licence gives you activation, security updates and access to the normal Windows support channels.
For a small business the licence also matters for compliance. Running unlicensed or incorrectly licensed software creates audit and security risk, and mixed fleets of random editions make life harder for whoever looks after the computers. Choosing the right edition once, and standardising on it, saves time.
Home versus Pro
Windows 11 comes in several editions, but for most buyers the decision is between Home and Pro. Both include the modern interface, Snap layouts, virtual desktops, Windows Security, Microsoft Edge and the same core apps. Pro adds the management and security tools that matter once a PC is used for work. In well-established terms, that means:
- BitLocker drive encryption for protecting data if a laptop is lost or stolen.
- Remote Desktop host, so you can connect into the PC from another device.
- Join a work domain (Active Directory or Microsoft Entra ID) and use Group Policy.
- Hyper-V for running virtual machines.
- Windows Sandbox for testing unknown files in a disposable environment.
If none of those mean anything to you, Home is probably enough. If any of them does, Pro earns its price.
OEM versus retail
An OEM licence is intended for a new or rebuilt PC. In general terms it is tied to the first computer it is activated on and is not meant to be moved to another machine later. A retail licence is the boxed or full-packaged product, and under Microsoft's usual retail terms it can be transferred to a different PC when you retire the old one. OEM is typically the lower-priced route, and retail gives more flexibility. Always read the terms that come with the licence you buy.
Key specs explained
Software has fewer specs than hardware, but the ones below decide whether a licence works for you. These come from the product listing for our pick.

|---|---|---|
| Edition | Windows 11 Professional | Adds BitLocker, Remote Desktop host, domain join and Hyper-V over Home. |
| Architecture | 64-bit | Windows 11 is 64-bit only, so your CPU and apps must be 64-bit capable. |
| Language | English | Sets the install language; other display languages can be added later within Windows. |
| Licence type | OEM, 1 pack | One licence for one PC, intended for a new or rebuilt system. |
| Condition | New | Listed as new stock. |
| Manufacturer part number | FQC-10528 | Useful if you need to match it to an order or compliance record. |
| Warranty | 12 months listed | Check the product page for the exact terms. |
The hardware Windows 11 expects
Microsoft's published minimums for Windows 11 are a compatible 64-bit processor (1 GHz or faster, two or more cores), 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot, a TPM 2.0 chip, and a DirectX 12 compatible graphics card. Microsoft also offers a free PC Health Check app that tells you whether a particular machine passes. Run it before you buy, because no licence will make an unsupported PC officially supported.
How to choose
Work through this checklist in order. Most people will have an answer by step four.
- Check the PC is Windows 11 compatible. Run PC Health Check or look up the CPU generation, and confirm TPM 2.0 and Secure Boot are present and enabled in the BIOS or UEFI.
- Decide Home or Pro. Choose Pro if you need drive encryption, Remote Desktop access into the PC, a work domain, Group Policy or virtual machines. Otherwise Home is fine.
- Decide OEM or retail. If the licence will live on this one PC for its whole life, OEM is a sensible fit. If you swap machines often, or want the flexibility to move the licence, look at retail.
- Count your machines. Each PC needs its own licence. Buying several of the same edition keeps your setup consistent.
- Plan for apps. Windows does not include Word, Excel or Outlook. If you need them, budget for an Office product at the same time.
- Plan for security. Windows Security covers the basics, but some buyers add third-party protection for extra features across several devices.
Common mistakes to avoid
- Buying Pro "just in case". If you will never use its extra tools, the difference is better spent on RAM or storage.
- Buying Home and needing Pro later. Upgrading editions is possible but adds a step and cost, so decide up front if you know you need remote access or encryption.
- Ignoring the TPM and Secure Boot requirement. This is the most common reason a Windows 11 install fails on an older PC.
- Mixing up the edition and language. Check the title for edition, bit-ness and language before you order.
- Expecting a licence to fix a slow PC. If a machine is slow on an old hard drive, a fresh install helps, but a solid-state drive helps more.
Our pick: Microsoft Windows 11 Professional OEM 64-bit
Our pick is Microsoft Windows 11 Professional OEM 64-bit English, 1 pack, currently $359.99. It suits anyone building or rebuilding a PC who wants the full set of business-ready features, and it is the edition we would standardise on for a small office.
What it does well
- Gives you BitLocker, Remote Desktop host, domain join, Group Policy and Hyper-V in a single edition.
- Pro is the sensible baseline for work PCs, laptops that leave the office, and anyone who connects to a company network.
- OEM licensing is a lower-priced route than a full retail package for a machine that will stay put.
- Listed as new, 64-bit and English, so it is a straightforward match for a typical Australian setup.
Limits and who should not buy it
- Do not buy it if your PC fails the Windows 11 hardware check. The licence will not change that.
- Skip it if you only browse, stream and write documents, because Windows 11 Home OEM costs $110 less.
- If you expect to move the licence between computers over the years, an OEM licence is not designed for that, so consider retail terms.
- It is the operating system only. It does not include Office apps, and Microsoft notes that some apps and games are sold separately.
Alternatives in our range
Here is how the main pick compares with other software options we stock. Prices are current at the time of writing.
| Product | Key difference | Price | Best for |
|---|---|---|---|
| Windows 11 Professional OEM | Pro features, OEM licence | $359.99 | Work PCs and new builds that need encryption and remote access |
| Windows 11 Home OEM | Home edition, OEM licence, key only | $249.99 | Home PCs and budget builds |
| Windows 11 Home Retail USB (HAJ-00090) | Home edition, retail version on a USB flash drive | $269.99 | Buyers who want retail packaging and a USB installer |
| Office Home & Business 2024 | Office apps, not an operating system | $439.99 | Anyone who needs Word, Excel, PowerPoint and Outlook |
| Norton 360 Standard 10GB AU | 12-month security subscription for 2 devices | $99.99 | Extra protection on top of Windows |
The first three are operating systems, so you only need one of them per PC. The Office and Norton products are add-ons that sit on top of Windows rather than replacing it.
Which one to pick
- Need remote access or encryption: Windows 11 Professional.
- Just need a clean, simple PC: Windows 11 Home OEM is the budget choice.
- Want a retail version: Windows 11 Home Retail USB.
- Need to write and calculate: add Office Home & Business 2024.
Setup and usage tips
- Back up first. Copy anything you want to keep to an external drive or cloud storage before a clean install.
- Update the BIOS or UEFI. A current firmware version avoids many install and driver problems, and is where you turn on TPM and Secure Boot.
- Install on a solid-state drive. It is the single biggest improvement in boot time and everyday responsiveness.
- Sign in, then update. After the first sign-in, run Windows Update until it reports nothing outstanding, and install your graphics and chipset drivers from the maker.
- Turn on BitLocker (Pro). Store the recovery key somewhere safe and separate from the PC.
- Create a local admin and a daily account. Use a standard account for everyday tasks and keep admin rights for changes.
- Record your licence details. Keep the licence information with your records so you can show it if asked.
- Set up File History or a backup schedule. A fresh system is the best time to build the habit.
Who is it for
- Small business owners setting up office PCs that need encryption and remote access.
- PC builders who have a new motherboard, CPU and drive and need an operating system.
- IT-minded home users who run virtual machines or connect remotely to their desktop.
- Remote workers who join a company domain or manage work devices.
- Anyone rebuilding a PC after a hardware upgrade or a drive replacement.
FAQ
Is Windows 11 Pro worth the extra over Home?
If you need BitLocker, Remote Desktop host, domain join, Group Policy or Hyper-V, yes. For everyday browsing, streaming and documents, Home does the job.
What does OEM mean?
OEM licences are intended for a new or rebuilt PC and are generally tied to the first computer they are activated on. Retail licences usually allow transfer to another PC. Read the licence terms for the version you buy.
Will Windows 11 run on my older PC?
Only if it meets Microsoft's requirements, including a compatible 64-bit CPU, 4 GB of RAM, 64 GB of storage, UEFI with Secure Boot and TPM 2.0. Run the free PC Health Check app to find out.
Can I upgrade from Home to Pro later?
Yes, Windows supports an edition upgrade, but it adds cost and a step. If you already know you need Pro features, buy Pro first.
Does Windows include Word and Excel?
No. Windows is the operating system only. For the office apps, look at Office Home & Business 2024 in the table above.
Do I need antivirus on Windows 11?
Windows includes Windows Security, which covers the basics. Some buyers add a third-party product such as Norton 360 for extra features across several devices.
