In some systems when you try to upgrade from Windows 10 to 11, you may face an error that says ‘This PC can’t be upgraded to Windows 11’ and that you need a Cfosspeed driver to do so.
cFosSpeed is a network driver that usually comes pre-installed with some of the ASUS, GIGABYTE, ASRock, and MSI motherboards. Missing this driver can prevent your Windows PC from upgrading to Windows 11. Cfosspeed is a program that is integrated into the existing internet connection to optimize data transfer and speed with Traffic Shaping and Prioritization. It increases your network speed while reducing the ping.
Your computer driver pack usually installs cFosSpeed. If it is not part of your driver pack, you can manually install the cfosspeed driver through the MSI companion app Dragon Center (MSI boards) or using the Cfosspeed shareware app.
Install Cfosspeed Driver through Dragon Center App (for MSI Users)
MSI Dragon Center usually comes pre-installed on most MSI computers or systems with MSI motherboards. It is a one-stop interface for controlling all MSI components, desktop systems, and peripherals. Installing this app will automatically install Windows 11 compatible Cfosspeed driver.
You can download Dragon Center from MSI’s official website (link below). Click on the ‘Download Now’ button on the webpage to initiate the download (a zip file). Once you finish downloading the file, extract and install the Dragon Center app.
After installing the Dragon Center software on your PC, reboot your system and try upgrading your Windows 10 PC to Windows 11. The driver issue should be fixed. If you are using any PC other than MSI, then try the next method.
Install Cfosspeed Driver with cFosSpeed Software
cFosSpeed is a software solution for traffic shaping which reorders Internet data packets to improve transfer rates while maintaining minimal Ping. This software attaches a new driver to the Windows network stack where it can monitor the network traffic. All the data packets flow through this driver.
Installing this software will automatically install the necessary driver for your Windows 11 upgradation. Here’s how you can install cfosspeed software on your computer:
Visit the cFosSpeed download page with this link – cFosSpeed. Then, click the ‘Download cFosSpeed’ button under the cFosSpeed – Version 12.00 (version may change).
Once downloaded, locate the file and install it. After the installation is complete, the driver will be installed and a small Cfosspeed status window will appear at the bottom of the screen and icon in the notification area.
If the cFosSpeed stable version didn’t install a compatible driver, you can try installing the beta version. To do that, click the ‘Download current beta (12.01.build 2516 version)’ link under the Download button on the cfosspeed download page.
On the next page, click ‘cfosspeed-v1201-build2516.exe’ (the versions may change because the software is constantly updated) under the Internet Accerlation via Traffic Shaping section. After it’s downloaded, install the program to install the cfosspeed driver.
If you already have cFosSpeed software on your computer and yet you still get the error, it is probably due to an outdated driver. By downloading and installing the latest version, you can get the latest cfosSpeed driver.
But by doing so, it will convert your licensed copy of your software to shareware. When you try to do this, you will get the following warning, click ‘OK’ for that.
After that, you can get an update of your original licensed software from the same place where you got it originally.
Upgrade to Windows 11 using a DVD or USB
If the problem still persists, you can make a clean installation of Windows 11 using bootable media (DVD or USB). But by doing this, you won’t be able to roll back to your previous Windows version. So, make sure to take a backup of important files of your C drive before installation.
If you want to install Windows 11, you can use the media creation tool to create a bootable medium (USB stick or DVD). Follow these steps to do that:
Go to Microsoft’s official Windows 11 download page, scroll down to the ‘Creating installation media for Windows 11’ section, and click the ‘Download now’ button.
Then, locate the downloaded file and double-click on it to run the wizard. For this, you need a blank DVD or USB drive with at least 8 GB storage capacity.
On the Windows 11 Setup window, click ‘Accept’.
Next, choose the language and edition and click ‘Next’.
Then, choose the media you want to use and click ‘Next’.
This will take several minutes to complete the process. Once it’s done, boot your computer from the bootable media to install a new Windows 11 OS.
You can also download the ‘Windows 11 Disk Image (ISO)’ file and use that file to burn a bootable DVD or create a bootable USB using third-party software (like Rufus).
To download an ISO file, choose the OS version from the drop-down under the Download a Windows 11 Disk Image (ISO) section on the same download page and click ‘Download’.
Then, choose the language and click ‘Confirm’.
Then, click the ’32-bit or 64-bit download’ button to download the iso file.
When you make a clean installation of Windows 11, you won’t face issues like cfosspeed driver missing error.
