Windows 10 Product Keys
The Windows 10 product key is a 25-digit character code. It looks like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.

To get Windows 10 activated, you have to enter a genuine product key. But if you skip the activation process, you will have a free trial period of 15 days. And when the expiry period ends, you will have to enter a genuine product key to continue using the operating system

Frequently Asked Questions
Product ID vs. Product Key
Many people don’t know the difference between a product ID and a product key. A product ID identifies the version of Windows your computer is running. A product key is the 25-digit character key used to activate Windows.
If you have already installed Windows 10 and you don’t have a product key, you can buy a digital license to activate your Windows version.

Upgrade vs. clean installation
Another common question people ask is whether they should perform a clean installation or upgrade Windows 10. If you have a custom PC and you want to install Windows 10 from scratch, you will need to format the hard drive first.
Here are the advantages of performing a clean installation:
- You can start fresh without any pre-installed trial programs
- Gives you total control over the apps you need on your PC
- Reduces the possibility of errors and other related issues
If you have updated to Windows 10 from an activated version of Windows 7 or 8, you will not need an activation key. That’s because there is a connection between the Windows license and the hardware you used while updating Windows. So, the upgrade will go through without providing a product key.
If you want to install Windows 10 on the same computer, you will not need:
- To download the IOS file
- To use DVD media or USB drive
- To install from scratch by running the setup
When installing the Windows 10 set up, you simply need to skip the step that asks you to provide the activation key. When the installation process is complete, Windows 10 will activate automatically when you connect the computer to the internet. That’s because Microsoft recognizes that you have performed the clean installation process on the same machine.

Product keys are one of the ways software developers protect their products against piracy. Unfortunately, they're easy to lose, which can be a real problem if you need to reinstall Windows or any other software from scratch
If you've bought a desktop PC or laptop with Windows 10 already installed, you'll probably find its product key on a Certificate of Authenticity sticker on the the case or in the included paperwork, but not if you've built your own PC and installed the operating system yourself.
Many other applications also require product keys if you reinstall them – including Microsoft Office – and if you've lost the email you received when you first installed them, you could be in real trouble later on.
Product key finders only work for software that's already installed, so download one and make a note of all your keys now, so you're prepared in advance.
1. Belarc Advisor
A wealth of information about your hardware and software
Belarc Advisor is primarily a tool for gathering information about your Windows system, including hardware, security updates and product keys.
Whenever you run Belarc Advisor, it automatically checks its database for software definitions – essential for finding keys for new programs. After that, it scans your system and presents the findings in an HTML page in your default web browser. Scroll down to 'Software licenses' to find serial numbers and product keys for Windows, Office and many other applications.
Belarc Advisor offers a wealth of other information, including details of your antivirus software, connected hardware, and other devices on the same network. It also offers a security benchmark score, though sadly this is only available for Windows 7, Windows Vista and Windows XP Pro.
Belarc Advisor's scans are fast and offer so much more information than just serial numbers, it's our favorite free product key finder.
2. Abelssoft MyKeyFinder
Displays your Microsoft product keys in a clear, searchable list
There are two versions of Abelssoft MyKeyFinder: free and paid-for. Both will find Windows and Microsoft Office product keys but the Plus edition (£8.90 – about US$10, AU$15) will also scan external hard drives and find Wi-Fi passwords.
After MyKeyFinder has scanned scan your PC’s registry the results are presented in a clear list, ready to be copied to the clipboard with a single click. Unlike many product key finders, MyKeyFinder won’t throw up duplicate keys and the results can be searched and filtered.

You can also add programs and keys not detected by MyKeyFinder as standard, then export the full list as a PDF so they’re all in one convenient location.
3. LicenseCrawler
Find the keys for Windows and a wealth of other software
LicenseCrawler will find the license key for pretty much any application that has one, and it's free for home use. Its scan of the Windows registry takes a long time to complete – even if you select the 'high speed' option – but you can limit its scope using the blacklist and whitelist filters.
LicenseCrawler is distributed as a portable app, meaning you don't have to install it on the Windows system you're scanning – just download the zip file, extract its contents and run LicenseCrawler.exe. This is particularly handy if you have several PCs; just download it to a USB stick and you can just plug it in and run it on any of them.
The only downside of LicenseCrawler is the occasional pop-up ad, but finding product keys isn't a task you'll be performing every day, so they're only a minor inconvenience.
4. Windows Product Key Viewer
A quick way to find your Windows product key, but nothing else
Windows Product Key Viewer is super fast, taking barely a second to scan your system and present the results. That's because, as the name suggests, it only supplies the product key for your operating system.
That shouldn't necessarily put you off though. Although it doesn't find serial numbers for other applications, it does provide some extra information about your OS, including the registered user, install date and last boot time, and it's compatible with versions of the operating system from Windows 10 all the way back to Windows 95.
Take care when downloading the software – the site includes some ads that look like download buttons for the software, but are in fact unrelated. Only click the link 'Download Windows Product Key Viewer'.
5. Free PC Audit
A super simple way to find your Windows 10 product key
Free PC Audit is another portable application, and doesn't even come as a zip archive – just download the exe file and run it to begin scanning.

Like Belarc Advisor, Free PC Advisor provides a wealth of information about your whole system – not just its software – though its interface isn't quite as intuitive. It's compatible with all versions of Windows, from NT all the way through to Windows 10, but doesn't find keys for Microsoft Office or any other software.
It also provides lists of all installed software and running system processes, though this information is readily available through Windows itself.
