Does your PC currently run Windows 11 Home Edition, and would you like to upgrade to the Professional Edition at an affordable price? If so, this license is for you. Note: it only works on PCs running an activated copy of Windows 11 Home; if you’re looking to install Windows 11 from scratch, or need a license for your VM, consider one of our Home or Professional licenses instead.

Windows 11 Professional includes everything you’ve already got in Windows 11 Home Edition, but adds the following features that will appeal to those in a work environment as well as power users:

  • Full BitLocker drive management: encrypt entire hard drives (including USB drives) for greater security
  • Domain connections: access your home or work network to share files, print remotely and more when away from your deskUpdate deferrals: Windows 11
  • Professional allows you to control when Windows updates are applied
  • Virtualisation: Hyper-V means virtual machines can be run directly from Windows itself without any third-party software – perfect for testing or developing new software
  • And much more: including sandboxing, Assigned Access for kiosk setup, Remote Desktop host, Local Policy Group Editor and higher hardware limits.

Upgrading is simple: once purchased, open Settings on your Windows 11 Home PC and navigate to System. Scroll down and select About, then scroll down again to the Related section. Click “Product key and activation” and click the Change button next to Change product key to input your Windows 11 Professional Upgrade product key. Follow the prompts, rebooting if prompted, to activate and complete the upgrade.

Remember, this Windows 11 Professional Upgrade can only be used to upgrade a PC running an activated copy of Windows 11 Home.

Includes a 1-PC upgrade license.

Performance Issues?

Most system performance issues are often a result of other software clashing with your brand new software. For instance, security software can clash with a background process, such as a system maintenance tool or defragmentation software. Another cause of system slowdown, is a result of two software applications performing a similar task. As an example, Windows includes a firewall switched on as a default. Your new security suite is likely to include a firewall. You only need one firewall running. In this example, try turning off your system firewall.

Uninstalling Your New Software

Occasionally you may need to either temporarily or permanently remove your new software.

On a Windows computer, go to the Control Panel and choose Programs and Features. Locate the program within the list, then click it to highlight it. Finally, click the Uninstall button at the top of the list and follow the instructions to remove the program from your PC.

On an Apple Mac computer, using Finder, locate the Applications folder. Within the Applications folder, find the name of the application you wish to remove. Simply drag the icon to your Trash icon in your dock. Empty the Trash to remove the files from your computer.

Still Having Problems?

If you cannot solve your system performance issues or are struggling to remove your software, we advise contacting the software manufacturer. If you placed an order, see the section in the order which states Support options. Alternatively, go to the Contact Us page to contact store support directly.

Frequently Asked Questions

Find quick answers to the most common questions about our services and platform

How Do I Order Software?
Simply select the software you want to order by clicking the "Buy Now" button or, where the option exists, clicking on "Upgrade". The upgrade option enables you to upgrade from a previous version of the software. When you click "Buy Now" you will be taken to your shopping cart, powered by PayPro, where you can choose a payment option and then receive your download and serial code within seconds, after making your payment.
What Is The Extended Download Insurance?
When you order software online, you receive a digital download and a serial code by email. You normally have 30 days from placing the order to download your software, if you need to download again in the future. You can choose to extend this to two years, enabling you to login to your account and find your download, serial code(s) and your original invoice. Ideal if you need to re-install your software, suffer from a system crash or buy a new PC. Simply head to the "My Account" section on this store to access previous orders.
How Do I Access My Order, After Ordering?
You can find your order in your store account for 30 days after ordering. You need a store account and, for security reasons, the email address used in the order, must match your store account email. Simply create a store account (if you haven't already) and login to find your order information. If you purchased 'Extended Download Insurance' you can find and access your order for upto two years from the date you placed your order, rather than the standard 30 days.
Why Are Some Prices Dynamic?
If you are based in New Zealand and you see prices in NZD, you may see a different price in your checkout than we advertise in the store. There's a good reason for this - software suppliers set their prices in USD, GBP and EUR, with NZD and other prices calculated based on the exchange rate and often between USD and NZD. Therefore some prices may be slightly cheaper or more expensive than the advertised price as the prices in the checkout are calculated, on-the-fly, from USD. This does not apply to customers in the EU, UK, US, Canada and Australia.
Why Was My Card Declined?
In most instances this will be due to fraud protection from your credit card provider. Although you have protection when you purchase goods, online, through your credit card, your company may decline a large order or an order made through an online store for the first time. If your card is declined, we suggest you speak with your card provider and/or your bank. You can also pay through PayPal, Google Pay, Apple Pay, wire transfer or other payment formats.
Can I Ask For A Refund?
We strongly suggest you download and test trial software before placing your order. Trial software is provided to enable you to determine whether it's applicable for your system and meets your requirements. Once you are happy with your trial software, place an order. Digital downloadable software often cannot be refunded unless the order was placed in error and the order remains unused. Activated software cannot be refunded as the code becomes the property of the customer and cannot be resold or reused. If you ordered in error or there is another problem with your order, contact PayPro directly for a refund.
Who Keeps My Order Information?
Your transaction is between yourself and our e-commerce provider, PayPro Global. PayPro will NEVER re-use your information, pass on to a third party and will not contact you unless you contact them with a query. Your credit card information is not kept on file and is not stored by any third party. If you ordered Extended Download Insurance with your order, we retain basic information about your order on our secure server. This includes your name, email address (required to access your account), serial codes ordered and download links to your software. No-one has access to this information apart from yourself. This information is only available once you have registered your account using the email address you used to place the order.
