Did your PC include Windows 11 Home and you're thinking about moving up to Professional? This is a simple upgrade from Home to Professional which will then offer you the additional Professional features for a competitive price. To upgrade, it's a case of adding your new Professional license to "Change Product Key" in your existing Windows 11 Home setup. Windows will then update, reboot, and you'll have a fully activated Windows 11 Professional.

Windows 11 Professional includes features of Windows 11 Home, plus important business functionality for encryption, remote log-in, creating virtual machines, and more. Get fast start-ups, a familiar yet expanded Start menu, and great new ways to get stuff done, plus innovative features like an all-new browser built for online action and Cortana, the more personal digital assistant.

What Windows 11 Professional enables you to quickly connect to another 'domain', whether this is your business or school to use network files, servers, printers, and more. Ideal for taking your work on the road when you still need access to the office network. Professional also gets additional security with BitLocker to help protect your data with encryption and security management. Best of all, create and host virtual machines using Hyper-V, which is ideal for testing new software or, if you're a developer, how your software performs on a brand new fresh OS.

A Windows 11 Professional upgrade can be used to upgrade from an activated 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.
