If you recently started using Windows 10, you may have encountered an issue where everything starts to slow down a lot. If you ended up looking at the processes running in Windows 10, you may have noticed a certain process that consumed a large part of your CPU.
At least that's what happened to me on one of my Windows 10 machines. I installed Windows 10 on several computers and all of them worked well until I installed it on a Lenovo laptop. When I checked the task manager, I saw that the Host process by the Device Association Framework (daHost.exe) occupied almost 90% of the system CPU! Normally, it should be zero and use only a few MB of RAM.
If you are seeing this running on your system, then the problem may be with an outdated driver running on your system. The process is used to associate wireless and wired devices with Windows. Since Windows 10 is fairly new and is updated twice a year, there is still a lot of hardware out there that does not yet support Windows 10 by providing compatible drivers.
You can find out if the hardware is causing the problem by going to Device Manager and checking for any yellow exclamation marks. You can do this by going to the Control Panel and clicking Device Manager.
Then check for any yellow exclamation marks on network cards, display cards, etc. If you see one, then it's definitely related to that piece of hardware and you probably need to find a driver for Windows 10. If you can't find a driver for Windows 10, try downloading the latest version of the Windows 7 or 8.1 driver. . Then you can install it in Compatibility mode.
If none of the drivers used are working, the only other option you may have until a new disable device is released. You can do this by right clicking on the device in Device Manager and selecting Disable .
Of course, you won't be able to use the device if disabled, but at least you will be able to use Windows 10 without the high CPU usage. If you have tried all this or if there is nothing in Device Manager that shows a problem, post a comment here and I will try to help you. To enjoy!
