Device Association Framework High CPU Usage in Windows 8?

If you have recently starting using Windows 8, you may have run into an issue where everything starts to run really slow. If you ended up looking at the processes running in Windows 8, you may have noticed a certain process eating up a lot of your CPU.

At least that’s what happened to me on one of my Windows 8 machines. I have installed Windows 8 on several computers and they all worked fine until I installed it on a Lenovo laptop. When I checked the the task manager, I saw that the Device Association Framework Provider Host (daHost.exe) process was taking up almost 90% of the CPU on the system!

If you’re seeing this running on your system, then the issue could be with an out of date driver running on your system. Since Windows 8 is so new, there is still a lot of hardware out there that does not yet support Windows 8 by providing compatible drivers.

You can tell whether it’s hardware causing the problem by going to Device Manager and checking for any yellow exclamation points. You can do this by going to Control Panel and clicking on Device Manager.

Then check for any yellow exclamation points on network cards, display adapters, etc. If you see one, then it’s definitely related to that piece of hardware and you probably need to find a Windows 8 driver. If you can’t find a Windows 8 driver, try downloading the latest version of the Windows 7 driver. Then you can install it in Compatibility mode.

If none of the drivers you are using are working, the only other option you might have until a newer is released is to disable the device. You can do that by right-clicking on the device in Device Manager and choosing Disable.

Of course, you won’t be able to use the device if it’s disabled, but at least you’ll be able to use Windows 8 without the high CPU usage. If you tried all of this or if there is nothing in Device Manager showing a problem, post a comment here and I’ll try to help. Enjoy!

    I noticed the same thing when my Dell XPS 15Z woke up and the fan was racing. Device Manager doesn’t indicate any issues.

    Device Association Framework Provider Host is using 60%

    I’ve recently come to have problems with this. My device association framework provider host is taking up to 90% of my CPU. When I look into the device manager, however, there are no yellow exclamation points. Any help would be appreciated.

    I got a new Toshiba Satelite and started installing the software I use, and transferring user data. All went well until last additions

    a) I installed and used Eudora 7.1, which seems to run, except it is often “Not Responding”;
    b) I also plugged in old scanner (Visioneer One Touch), which wasn’t recognized. Device manager doesn’t indicate any problem with any device, but scanner isn’t seen by device manager.

    Suspect system is flummoxed by ancient hardware.

    I looked through all of my devices and none of them have the yellow exclamation mark but yet I still have a high cpu usage from Device Association Framework Provider Host. Any help?

    My HP Notebook 2000 has had this problem for a few days now. Many of the apps I use just randomly shut down, and my Device Manager hasn’t indicated anything either. The Device Association Framework Provider Host is using anywhere from 75-89%.

    Hi,
    My CPU is at 90%+ due to the Device Association Framework Provider Host and there there is nothing in Device Manager showing a problem (no yellow exclamation points). This is a brand new HP Pavillion machine from Costco with Windows 8. Don’t know what to do. Can you help?

    yeah mine is using up 88%-99% of my cpu but none of the devices have exclamation marks. Its a brand new hp g7 2269wm laptop that came with windows 8 and I don’t have any external devices plugged in (except for an sd card in readyboost but I unplugged it and the problem wasn’t fixed)
