Fix Windows Shell Experience Host process using too much memory/CPU

The Windows Shell Experience Host process may use quite a bit of memory or CPU when it is running.

To find out whether this is the case on your machine running Windows 10, use the keyboard shortcut Ctrl-Shift-Esc to open the Task Manager.

Click the "more details" link at the bottom left of it and locate the Windows Shell Experience Host process in the listing. You may click on name to sort the processes alphabetically which may make it easier to find it in the listing.

The process name is ShellExperienceHost.exe and on the right of it you will find its cpu and memory use.

Use may be normal, as was the case on the Windows 10 computer we tested this on, or too high. Too high means that you will see constant or higher than usual cpu and memory usage.

The description simply repeats the name of the process which is not helpful in finding out why it is running.

While the full functionality of the process is unclear right now, it is linked to the desktop background of the system, or more precisely, to the automatic color changing of interface elements based on the wallpaper's dominant color.

Users of Windows 10 who reported these issues managed to resolve them by turning off the automatic color changing based on the wallpaper. Note that the feature is enabled even if you only use a single wallpaper.

To resolve it, do the following

start color

  1. Tap on the Windows-key, type Settings and hit enter.
  2. Navigate to Personalization > Colors.
  3. Turn off "Automatically pick an accent color from my background", and select a static color instead.

You should notice that cpu and memory go down after the change. There may be more to the process than just that but making the change fixed it on several systems that ran into the issue in the past.

    What mental age of reader are you targeting with the first sentence? 10?

    Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.

    If your paymaster Microsoft permits it, of course.

      I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.

    bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.

    Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.

    I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:

    1) Too young to remember a time before W10 and W11 (doesn’t know better)

    2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)

    3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””

    4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows

    5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss

    Obviously that doesn’t cover everyone, there’s also the category that:

    6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now

    Have I missed any group off this list?

      You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.

      Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.

    1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.

    2. I have installed it in a 11 years old computer, and no problems at all.

    3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.

    This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
    Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.

    Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.

    Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.

      Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.

    While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.

    My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
