How To Fix Slow Internet After Downloading Windows 11 – Easy Steps

Windows 11 has been available for just over two weeks, and so far it appears to be stable.

Internet speeds tend to suffer when an operating system is updated or installed again. This is often attributed to updates that are installed in the background. At times, you may find that some services are not compatible with the new operating system and need to be completely discontinued. If your system is marked as unfit for Windows 11 update, please wait a few months for driver updates to be available for your various hardware components.
