A driver update tool provides you with new driver versions for your hardware, and can also save a backup of current drivers before making any changes. It is generally advised to use a driver software as updates can be time consuming and complex. Incorrect hardware drivers can lead to more serious issues than just a faulty installation. However, even if you are good at locating, installing, and upgrading drivers for the TL-WN721N, one can still waste lots of time and be very frustrated with this endeavor. It is often hard to find a right solution to a TL-WN721N hardware-related error by visiting TP-Link's website. The positive aspect is that once you update your Wireless Adapter's driver it will stop crashing. Device drivers can be functional one day, and then stop functioning the next day due to a number of causes. It is possible to link TL-WN721N errors to corrupt or obsolete system drivers. I'll have to test it further to make sure the adapter works as normal, but until then it looks great.Typically, you should update TL-WN721N device drivers after major Windows updates. NT Kernel & System is using 0% of CPU and 24KB of RAM as normal. It did install drivers, and all seems good right now. To fix it, I went to Device Manager and got Windows to search online for drivers for my device. I don't know if this is the case for all users, but I thought I'd mention it in case it is. Seeing as I had experienced this problem only after installing the Windows 8.1 driver, I assume that said driver is not suitable for Windows 10. After doing a bit of research, I found that this is normally down to a dodgy driver.

Later, however, I experienced huge slowdowns on my PC, FPS drops in all my games, and noticed that the CPU usage and memory usage of the NT Kernel & System process was through the roof. I manually installed it just as they showed me to, and all seemed fine. Okay, after raising a ticket with TP-Link support they suggested to use the Windows 8.1 driver. Are you using the windows 10 built-in driver or driver for Windows 8.1?
